[@rickdoe111]

LX 470 Thanks for the video! I watched a couple of other videos and came up with an easier, faster and cleaner way. I brought your bucket. Then I pulled the hose going to the radiator and place my refill hose to replace it. After refilling after every 2 quarts my fluid started to look clear after 11 quarts. Therefore, after 12 quarts I pulled my refill hose and reconnected the old hose I was emptying from. This way is a total recirculation of the fluid and no touching the transmission refill plug. Then I just followed your instructions afterwards and done! If I try it next time I would figure out a way to keep the refill funnel up in the air by itself so I don't have to stand there during the slow refilling! Thanks again!

Thanks and you're welcome. The process for any Toyota sealed transmission would be similar. The only question would be does the temperature at which you check the level at change at all. You can get access to the information through the Toyota Tech Information website. You can buy a $20 / 2-Day Subscription and download the info. The website does have a little bit of a learning curve, but once you know how to use it, you can get any information you want for any Toyota/Lexus/Scion vehicle. When I first used the website years ago, I was successfully able to use my Mac laptop. Then one day I had issues accessing the site and I called for help. The lady helping me said I needed a windows based computer now because their system changed so I bought a used Dell Laptop running windows and haven't had issues. But, recently, some guy told me he successfully navigates the website with his Macbook and using Windows is only for the Tech Stream program. Anyway, I've blah blahed enough.

[@alanthomas3690]

Great video and what I do in Australian on my 100 series but always shifted through the gears to change the torque converter fluid as best I can while exchanging the fluid , like your thought’s Tim.

[@TimmyTheToolman]

Thanks Alan. Never thought about shifting through the gears when doing the exchange. Don't really know if it's necessary based off my experience. It appears to me all the old fluid is being pushed out of the torque converter without shifting based off how the fluid starts to look clean as the max quart capacity of the system is reached during the exchange. But, you got me thinking now. When you're getting the fluid level dialed in, the manual instructs to shift through the gears. Shifting through the gears takes some time through. Are you exchanging out 1 quart at a time like I did or are you moving more fluid than that on each round?

[@alanthomas3690]

@@TimmyTheToolman We use litres over here Tim so much the same fluid quantity and I get your point that it’s looking clear at the end of the operation but after the first top up go I go through the gears a couple of seconds each gear before I dump for the next fluid change , and same again again again , don’t know if it would get TC cleaner that way Alan.

Tim, i always drop the pan and change the filter when i do a trans fluid change. regardless of extra work it’s always worth it to clean the magnets and get a fresh gasket in there to ensure longevity.

[@TheDesertRat31]

Yep. This procedure works well. I've done it 3 times on my 08 4runner. When pumping out the old fluid, you can let it go 2-3 qts at a time. I built my own power fill jug with a 1gal garden sprayer. I took off the 1/4 turn valve because it seeped ATF out. I just fill it with how much I want to put in the tranny, then pump it up a bit. The one cool feature it the hook end. That makes it easy to keep the fill process a lot less messy. I might add a short piece of copper pipe bent in a J, or something.

[@TimmyTheToolman]

Thanks for the comment Bob. I personally feel more comfortable only doing 1 quart at a time. I realize there's no real load on the transmission, but I'd rather err on the side of caution and not run the trans that low for any length of time. Yeah, that Motive Power Fill Pump is basically a fancy garden sprayer.

[@joshstanman]

I also pumped out 3 quarts at a time when I've done this in the past with no ill effects. One quart at a time gets a bit tedious!

[@adrianw3985]

I have the A750F transmission in my 5th Gen 4Runner. I get 4 quarts out with a drain and fill. I wasn't surprised when you had to add more to get flow out of the level check tube. 2 quarts out on your pan drain is only half what I normally get.

[@TimmyTheToolman]

Good to know. It definitely appears his trans was under-filled. Amazing it was still shifting fine. How it got that way, who knows. Maybe it was serviced by someone and they under-filled it. I'm going to do a drain and refill at some point on the trans I replaced in the FJ Cruiser and I know that trans was properly filled because I did it. I'll be interested to see how much comes out. I've had people say on some of the Facebook pages I posted the video on that they get around 3 quarts out on a drain of the pan. The manual did say a pan drain produces 1.8 quarts. Weird. Thanks for the comment.

[@pmo1825]

Great instructional video! I think your half quart discrepancy was what was left in your fill hose between the J hook and the quarter turn valve. Strong work again Timmy ! Oh and I love the little note that ( I'm guessing ) your daughter left on the white board.;)

[@TimmyTheToolman]

I'm glad you liked the video. You might be right about the discrepancy. Can't remember what the whiteboard said. I don't have a daughter, but I have a wife.

[@robertmaybeth3434]

These guys are the best, they have a great way to change the ATF. There's several good reasons to change your ATF yourself mainly because if you do, your trans will probably outlast the car. In owning around a dozen cars and trucks, 10 with auto trans 2 with a stick, I always changed the trans oil in all of them every year or every two years tops. Most of the cars I ever owned had 200,000+ miles when I sold them, but not a single one ever needed transmission repair. That might be one reason why Toyota deleted the dipstick in the first place, which is a very un-Toyota thing to do, but there is more to it as usual. The reason why almost all automakers eliminated the dipstick and drain plug (the info is from a guy in the auto business, from a forum comment, so take it with a grain of salt) is that the US EPA quietly made an "arrangement" with the automakers to help reduce waste fluids from cars and trucks in general. So towards that end the automakers, again quietly, started deleting the ATF dipsticks from everything! (I'm convinced the EPA would weld the engine oil drain plug on and seal the hood if they could, and the fact is, BMW seriously considered, then thought better of, simply sealing the hoods on all their new cars (!)...this is a thing I'd dearly love to see them try, since the consumer reaction would be hilarious, unless you own a Beamer I guess!). I recognize the disposal of millions of gallons of waste oil is nothing to be taken lightly, but the fact is, such waste oil gets burned in millions of furnaces that are designed to use it... so why shouldn't EPA give rebates for such furnaces? Anyway Anyway, even though it's cold comfort to understand the REASON they deleted the ATF dipstick it does nothing to help us change our ATF as often as we'd like! ATF is a normal wear item same as tires or brake pads but they insist we treat the ATF as a "lifetime" product which it 100% is not! ATF made today has essentially the same service life as the fluid we've been using for over 50 years and, except for two additional words on the bottle, nothing about the ATF has improved enough to make it "LIFETIME FLUID". Auto lubricants are constantly improving, of course but trust me, they did not suddenly figure out how to make the world's finest ATF with voodoo spells or sorcery. Your ATF still gets dirty, thins out, and wears out, just as it always has, and that's why it needs to be changed - and there is nothing happening in the field of tribology so far that is going to change that anytime soon.

[@TimmyTheToolman]

We appreciate your comment. Yeah, ATF needs to be renewed. The whole lifetime thing is a bunch of BS.

[@pjames4413]

I recall some information that explained that the 'sealed-system' was designed to eliminate the free exchange of air to reduce oxidation of the tranny fluid, thereby extending the effective life of the fluid. ... I believe there must be a 'vent-valve' that is pressure and vacuum regulated (so no dipstick and no open venting).

I rolled 182,000 before doing a transmission service.My tundra drained three qts. Started cold drained 3 quarts added 3 ran thru gears.repeated three times. Run to temp. Adjusted level. Working great two years out.used Valvoline full synthetic checked after 30,000 miles fluid looked red. I attached 4ft, of 1/2" clear tubing to a funnel threaded from engine bay to filler hole .

[@TimmyTheToolman]

It's pretty amazing that you got away with not servicing the transmission for that long. From my research, the effective life of ATF is only 100k miles, and that's under perfect driving conditions, with the truck never being driven in the mountains or towing anything. In my opinion, you took away some potential life of your transmission by not giving it regular fluid servicing.

[@mrkopmana]

Thank you!

[@TimmyTheToolman]

You're very welcome Andrew!

[@benhoughtonmusic]

fantastic video, thank you! When you're running through the gears do you hold the brake pedal down or you've got the car on a lift with the wheels turning?

[@TimmyTheToolman]

You want your foot on the service brake. Even if your tires were lifted off the ground, the wheels don't need to be spinning. You're just shifting through the gears to make sure the transmission fluid has circulated thoroughly. Glad you like the video Ben. Good luck with the flush.

[@laurencanary7858]

Thank you for this helpful video! If you were to take the conservative approach of draining a few quarts and adding fresh fluid gradually over time, how many miles would you drive it between draining/adding more fluid?

[@laurencanary7858]

also was wondering whether cleaning the filter would be feasible rather than replacing?

[@TimmyTheToolman]

I wouldn't waste the effort on dropping the pan. Those fine mesh filters don't really need to be replaced unless you know the transmission was abused and didn't receive regular maintenance. The way I keep my transmission fluid in great shape is I do a pan drain and refill every 10,000 miles. Some might consider this overkill but I don't. You're only exchanging around 1/3 of the capacity every time. I subscribe to the old school recommendation of renewing ATF every 30,000 miles if the vehicle is driven hard. ATF can last up to 100,000 miles but that's only if you never hit higher temps like you do when driving in the mountains, 4wheeling or towing. If you drive on flat ground all the time and don't tow, I'd say you could get away with a drain and refill every 30k miles.

[@nattakiet1]

[@MrTomekimagda]

Thank you for great instructions. Is there a difference in checking the level (open drain) with the engine turned on and off?

[@CapWalks1]

Excellent how-to video. Question: wouldn’t it be better to pump the transmission dry, first - then filling the transmission once with fresh fluid instead of going a quart at a time?

[@TimmyTheToolman]

We like doing it one quart at a time. We don't like the idea of the transmission running that low on fluid. The safer technique of one quart at a time is what we recommend. We're glad you like the video and we appreciate you taking the time to comment. Good luck with the fluid exchange. Your transmission will thank you.

[@yak4fish]

Thanks for creating this guide! Question: I have an '08 4runner with the A750E with 180k. Fluid was changed at 100k. At around 170k I did a pan drain and fill 2x and each time the shifting and slight shudder from 4-5th gear was gone and acceleration response was noticeably better but only for what seemed like 30 or so miles. I did use valvoline maxlife instead of Toyota ws but was wondering if shifting on this GS was still good without shudder? Thanks again!

[@TimmyTheToolman]

The shudder hasn't come back with Thanh's GX470 but I don't know how many miles he's driven in it since the flush.

[@cuongandmari]

Hi Tim, thanks for the great video. Do you have to put the fill plug back in every time you add a quart? Or leave it out until after you check the over fill plug then put it back and torque it.

[@TimmyTheToolman]

Glad you like the video. No, you can leave the fill plug out for the process.

[@tarzan30809]

Thanks again Timmy, just getting ready to do this job on my son's 2015 Tacoma. In your video it seems the filling pump and hose are always conected to the transmission filling hole until the completion of the fluid exchange. It is that correct?

[@TimmyTheToolman]

Yes, that's correct. You can just leave it hanging in the fill hole during the fluid exchange process. Good luck with the job.

[@jeffcarbello9115]

Nice video, the correct way to do a hot change no dip stick. Though with fluid that dirty, if the miles were high I would have elected to drop drain pain and replace filter and gasket. What are your thoughts on using better ATF like AMSOil signature fully syn if car is out of warranty as seems alot folks find at higher mileage and colder temp weather it works much better.

[@TimmyTheToolman]

[@williamchiang8293]

Thanks Timmy great video! Just curious, any reason why you didn’t use OBD2 to check trans temperature? You did for 4runner.

[@TimmyTheToolman]

Yes, it's ok to leave the fill plug out and the tip of the pump in the trans. But, with the fill nozzle we used, the tip barely extends past the threshold of the transmission case. You couldn't want a hose pushed way in there, because if it catches something, you're just messed up big time.

I had to add some additional fluid on my ‘07 Tundra with the A750F transmission. When I got it to fluid level check mode after my three drain and fills nothing came out of the check plug so I added fluid through the open fill plug while the engine was running. Took about 1/2 quart of additional fluid before fluid started draining from the check plug. Great video!

[@DaddyBusAdventures]

About ready to do this myself. GX470 with a little over 260k miles and I have the same washboard road vibration around 40-50mph (the whole vehicle shakes), so hoping this will remedy that issue. I will stay on the cautious side and do a partial flush only, maybe 8qtrs, then repeat again in a few weeks and replace the rest. Since I am pulling a small offroad trailer with my rig now, I will also install a bigger external radiator to keep the trans temps lower. Recorded some temps on mountain passes in the 220-230 range which is fore sure too hot for my liking.

[@TimmyTheToolman]

Hope the fluid exchange worked for you. Recording high trans temps in the mountains is normal. Even with using the trick of turning overdrive off to lock up the torque converter doesn't always work based on the speed you're traveling up the grade. The key is to know when it's prudent to pull over and give your transmission and engine a break. That could be the difference between happily continuing your trip or being stuck when you either blow your trans or engine. Knowledge is power. The fact that you monitor your temps puts you way ahead of the game.

Three years ago I have my 2006 tundra to local dealer with 13 quarts for a flush with the machine. I got the truck back think it was done but once the transmission would heat and I would come to stop it would shudder and bump. So I opened the pan drained the oil out refilled it as per the factory service manual after getting the overflow plug dripping i closed it and it has ran fine since. I would not recommend the flush via the machine as they don’t check if adequate fluid has been put inside.

[@TimmyTheToolman]

Thanks for the comment Andy. That's unfortunate they don't confirm the fluid level is good after flushing the system. You would think this would be part of the service. I guess it supports my belief that it's better to do it yourself instead of taking it to a shop. When you do it, you know it was done right.

*PLEASE READ THIS COMMENT FOR IMPORTANT INFORMATION* **The cooling circuit for the A750F transmission is going to depend if your rig came stock with an additional external cooler or you just have the standard internal cooler inside the radiator. Regardless of which setup you have, you would want to follow the metal "SEND" line from the transmission towards the radiator. That metal line will eventually change to a rubber line that connects up to one of the cooler nipples on the radiator. It might go from metal, to a rubber line, back to a metal line and then to another rubber line depending on how Toyota decided to plumb the circuit. The fluid flows through the cooler and then exits another nipple on the radiator. If you don't have an external cooler, the fluid will flow directly back to the transmission. If you do have an external cooler, the fluid will then flow to the external cooler and then back to the transmission. The reason why you want to understand how the fluid flows through the transmission cooling circuit is you want to remove the rubber "RETURN" line and install another 3/8" transmission hose directed into your graduated level container for this flush procedure. **If you're viewing this video but you don't have an A750F Toyota Transmission, this DIY flush procedure will work for your sealed transmission as well. You first have to figure out which metal cooler line on the side of the transmission is the send line and which is the return line. You might be able to find out this information online, but an easy way to figure out which one is which is with a infrared thermometer. Point the thermometer at one of the cooler line fittings on the side of the transmission and note the temperature. Now, check the temperature of the other fitting. The fitting with the higher temp is the send line. It's sending the hot transmission fluid to the cooler. The fitting with the lower temp is the return line because the fluid ran through the cooler, it dropped in temperature, and is now returning to the transmission. Once you know which is which, you want to follow the send line towards the radiator, follow the circuit so you know which hose is the return hose so you can disconnect it and add your own 3/8" hose for the flush procedure. The other piece of knowledge you need is the recommended temperature at which to perform the fluid level check procedure. You can find this out via the manufacturers manual for your vehicle which will usually be an online resource or you can maybe find this out by asking on a forum and somebody knows the answer. Once you know these two pieces of information, you can perform the flush procedure and accurately top off the system with fluid. **At the beginning of the video, I discuss the concern of performing a full flush on a transmission that was clearly abused that has dark and nasty fluid. I mentioned one theory about how the transmission could have issues after a flush. The other common theory that I didn't mention is the fluid could be holding suspended clutch (friction) material in it. The fluid lost most of it's optimal lubricating properties, and because of that, excessive wear happened with the clutch disks. Currently, the only thing keeping the transmission shifting and not slipping is all that suspended friction material in the fluid. Once you perform the flush, you lose all that friction material and now the transmission doesn't shift and/or it slips. As it happened, even though Thanh's transmission was clearly abused due to the condition we saw the fluid was in, the end result was the transmission shifted better after the flush. So, did we just get lucky or maybe the concern about performing a flush on an abused transmission is quite a bit overblown. It's hard to say if there is merit to this concern because there's conflicting experiences.

[@I_know_what_im_talking_about]

I couldn’t believe you didn’t mention the fluid being full of clutch pack material and helping an old trans to function in the video. That is literally the main risk in doing a full trans fluid exchange on an old car. There’s no way that sludge would form in the trans unless SEVERELY contaminated somehow. Transmission fluid just doesn’t sludge up naturally.

[@TimmyTheToolman]

Really good info, ive (wife car) had my GX a almost 2 years now and i think its time to drain and fill it. Drive fine, shifts fine, just dont know of the old owners did anything. Got it at 158k. Ive just never had an automatic before, only manual and i can do a clutch quick and easy. But automatics are scary man!

[@TimmyTheToolman]

@noahwise6938 Yeah, it sounds like your wife's rig is due for an ATF renewal.

[@bluedragon2824]

Tim, I have a 2014 RAV4 and the maintenance manual has no mention of changing the transmission oil thru the 120,000 maintenance (highest mileage the manual goes to). It does mention changing the transmission oil if operating under special conditions, like driving while towing, car top carrier or heavy vehicle loading. When should the transmission oil be changed if driven normally?

[@TimmyTheToolman]

The life expectancy of ATF depends on the temps it's been subjected to. ATF can last as long a 100,000 miles if the fluid temp never exceeds 170 degrees fahrenheit. If you drive at all in the mountains, you will be exceeding 170 degrees. As the temps go up the life expectancy goes down. When fluid loses its effectiveness to lubricate, excessive wear happens. Since I drive a lot in the mountains, I do a drain and refill of the pan every 10k miles to keep my fluid in good shape. This is what I recommend people do. If they want to wait a longer interval, then I recommend a full renewal every 30k miles. Performing fluid maintenance is cheap insurance. It might be overkill, but I'd rather err on the side of doing fluid maintenance too often than not enough and then be looking at a transmission replacement. It's a big and expensive job to perform.

[@DarwinWasBlind]

Video is very helpful!! I do have a question, I have seen that dropping the tranny pan allows you to clean the magnets and possibly even replace the filter. What are your thoughts on this?

[@TimmyTheToolman]

If the trans has an unknown history and it appears the trans wasn't taken care of (ie very dirty fluid), it might not be a bad idea to drop the pan to make sure the filter isn't majorly clogged. If the trans was taken care of pretty well, I don't think it's worth your time to drop the pan. I cut open one of these type of fine mesh trans filters on my 3rd Gen 4runner and it was probably 90-95% unclogged. As for the magnets, they can gather fine metal debris for the life of the rig in my opinion. It's not like the magnets get flooded with lots of debris. It's usually a very fine sludge of metal on each magnet. If a trans is taken care of, you really never need to drop the pan. You can also do what I've done on my rigs and add a magnetic in-line filter in your trans cooler return line. *Magnefine 3/8" Magnetic In-line Transmission Filter amzn.to/35p6heN The Magnefine filters are rated for 30,000 miles of use. It's a nice way to achieve extra filtration with very little work. I should have installed one of these for Rey, but I forgot when I installed a trans cooler for him.

[@richardmaxwell4489]

From what I understand that the 2020 and 2021 Tundra does not have an external transmission cooler is that true ? and if so is as strong as 2019 with a Transmission cooler, and so should the Trans fluid be serviced more often than the one with the Trans cooler ?.

[@TimmyTheToolman]

I don't if the 2020 or 2021 have a trans cooler. The lack of a trans cooler doesn't mean the fluid should necessarily be renewed more often. It depends how the vehicle is driven. People that drive in the mountains a lot, go 4wheeling, or tow should change their fluid more often because they will be pushing the transmission harder and thus hit much higher trans temps than someone who just uses their rig as a grocery getter. The key is to monitor your trans temps and base how often you renew your fluid with how you drive it.

@@TimmyTheToolman As an update I did the fluid flush from the radiator and after 2000 miles so far so good.

[@TimmyTheToolman]

@@drscopeify I think you got most of the fluid out if you did it just like we did it in the video. The color change I believe is because of the excellent detergent qualities of the new fluid. Your transmission had a build-up of gunk inside it due to the lack of fluid maintenance. The fluid is cleaning the transmission resulting in the fluid getting dirty looking.. Following up with this flush, I would perform just a drain and refill of the pan every 10k miles. You will notice as time goes on doing these regular drain and refills, your fluid will get cleaner and cleaner. Drain and refills is all I do with my transmissions and the fluid stays in great shape. It's a dilution process (mixing new fluid with old fluid) but it works well. Good job getting the flush done. Keep up on your maintenance and you're transmission will be happier. Happy Wrenching!

It may seem like that but it really isn't. The flush is simple procedure of drain a quart, add a quart until the fluid looks new, around 12 quarts. The fluid level procedure isn't hard either. Get the trans to the proper operating temp and open the overflow plug. If no fluid spills out, put the plug back in, add a 1/4 - 1/2 quart, get it back up to temp and remove the overflow plug again. Keep adding until when you remove the overflow plug, fluid comes out. Let the fluid drain until it becomes a trickle and put the plug back in and torque to spec. Done deal. It's not hard.

I appreciate your videos Tim. I learn a lot from all of them. Thanks for the time and effort to make these. A guy or gal should be able to do their own mechanic work like this, simpler stuff. The gist is, whether its sealed or has a dipstick, the procedure is the same for a flush - the only real difference being how you refill the transmission - sealed or not sealed. Obviously much easier to fill with a dip stick and no pump. I watched a guy on youtube completely drain his transmission - not a Toyota. He flush drained it until there were only bubbles coming out. Then refilled it. without any consequence, at least shown to the viewer. One difference in that case is there is no new fluid helping to push out old fluid and debris from any of the valves etc. That seems sketchy as the lack of fluid in the draining mode could allow parts to damage and in the refill possibly too much pressure in certain areas inside. I have an non CVT style automatic 2003 Tacoma A340 - I don't know if it is the F or the E. I wish there were more definitive answers about a full flush procedure actually causing a slip or stuck condition. I am tempted to flush mine out. I want someone to say its okay to do it. But maybe I will do a simple drain and fill two or three times and then if no issues just go ahead a flush it. Anyway, Thanks for your videos.

[@TimmyTheToolman]

Good to hear you're learning a lot from our videos. You are correct. Whether it's not sealed or sealed, the flush procedure is the same - drain a quart and add a quart until the fluid looks clean. The guy that just let all the fluid drain out at once is stupid. I don't care if the transmission has no load on it, I'm not going to starve the transmission of fluid and hope I didn't cause damage. It's also bad to let any pump run dry like he did. If your trans has never seen a service, it would be safer to do the series of drain and refills and do them gradually. Space them out by a decent interval like 3,000 miles or maybe do them timed with your engine oil changes. After the 3rd round, your fluid will be in pretty good shape. After that, I would do a drain and refill every 10,000 miles or every other engine oil change. That's what I do with my 4runners and I keep my fluid in great shape. On Thanh's GX470, with how black his fluid was, we took a risk doing the full flush and got lucky. Nobody is going to be able to give you a definitive answer if a flush will be safe unless they have a crystal ball and can predict the future. Good luck!

[@AZRubicon1]

I just flushed my 2004 GX470. 150k miles that had been sitting for 7 days. Rather than just removing the drain plug, I decided to see if anything would come out of the overflow plug. It was pouring out, it looked like a drain plug flow. With a measuring bucket under it I got nearly 1.5 quarts our of the overflow! Then removed the drain plug. Got another 3.5. Total was just under 5 quarts! Obviously not right. I have all records on the truck and have no record of it ever being done. So, after replacing crush washers and putting the plug and and drain bolts in, I removed the hose between the ATF cooler and hand pumped a gallon in with a simple Harbor Freight pump. Then did the 2-n-2 change with 2.5 more gallons (3.5 gallons total) used clear cups to see the progression of dirty to clean fluid. Nice-n-pink. Ran through the shifting and then a drive for 5 miles. Shifts beautifully as it always has. I am hesitant to let it drain through the overflow plug to a drip because I don't know if a previous owner broke it off if they pulled the pan. There is no need to ever pull this pan, the filter is not one that needs to be changed. So, @timmythetoolman what say you? If it ain't broke don't fix it? Meaning, should I drain it to temp with the overflow without knowing if the overflow valve in the pan is actually there? Pulling the pan is an option and I don't need another flush, it'd just be to check and see.

[@TimmyTheToolman]

I don't think the overflow tube is something someone could damage unless they are really trying to. I haven't personally seen what it looks like but I assumed its just a vertical metal spout that rises up from the bottom of the pan. When you're at the right ATF temp, any fluid that was able to spill over into the tube was excess. So, I don't think it's some sort of valve but rather a simple metal spout that really can't be broken. I just did a search on KZbin to see if someone shows what the overflow tube looks like in the pan and I found this video. kzbin.info/www/bejne/sKuQeaxujrijhpI So, I think you should go through the fluid level check procedure we detail in the video to make sure you have your level right.

I would still do the level check procedure. You don't know if the fluid level was good before you did the drain and refill. It's also a bit difficult to exactly measure what you took out and what you added back in. Even with a container with graduated level markings, if you drain out somewhere between the markings, you're doing a little guessing. Also, with the fluid pump, some fluid is left in the pump lines which can throw you off.

Good to hear Dave. Yeah, the procedure in the FSM is a bit convoluted. This is one of the reasons why I wanted to make the video to make the process more straightforward.

If not, add a half quart, get it back up to temp and check again. Keeping adding a half quart at a time until it spills out of the overflow port. Let it get down to a trickle and you're good.

If you're worried about potential problems after a flush, just start with a drain and refill of the pan. Wait around 3 k miles and do another one. Then follow that up with a 3rd one after another 3k miles. After the last drain and refill, the fluid will be in decent shape. After that, I'd recommend a drain of the pan every 10k miles or every other engine oil change. Regular drain and refills keeps your fluid in excellent shape. That's what I do with both my 3rd Gen 4runners.

People do 'exact replacement of drained fluids' at a specified temperature. How does this correct previous inexact exchanges? What is the purpose of the 'overflow drain plug' if the volume replacement procedure is followed?

[@TimmyTheToolman]

Exact fluid level exchanges works if the original level was perfect and you added back in the exact amount you drained out. I have containers with graduated volume levels. When I drain out oil into these containers, unless the level falls exactly on one of the level lines, there's a bit of guesswork on exactly how much was drained out. You could get close, but you'll be hard pressed to be spot on. The purpose of the overflow drain plug is to correctly dial in the fluid level. Without this method, there's a level of guesswork based off what I said above. Also, at some point, you might spring a leak in your transmission fluid system. How would you get the level back to full capacity after repairing the leak? The answer is the overflow plug.

[@TimmyTheToolman]

Hey Javi, I doubt I'll be doing a video for a RAV 4. It's a pretty big longshot. From this video, you have most of what you need to know to get it done. You first need to figure out which cooler line on the side of the trans is the send line and which is the return line. You can determine that by simply using an infrared thermometer and seeing the temperature of the lines. The colder line is the return line. Once you figure that out, you want to follow the return line forward to the radiator and remove the rubber return line off the transmission cooler nipple. You put your own hose on there and direct it into a bucket. Then you do the flush like we demonstrate exchanging 1 quart at a time. When you're finished with the flush, the only thing I can't instruct you on is the temp at which you check the level at for the RAV 4 transmission. If you have a windows based computer, you can access information from Toyota via their Tech Info website. You can buy a 2 day subscription for $20 and download all the information you want. There's a bit of a learning curve to using the program but you'll figure it out. Basically the information you seek will be found in the RM pages which stands for Repair Manual. When you get a page you want to download, you click on the printer icon and you can select to save is as a PDF on your computer. This is how I get the information I need for the newer Toyota and Lexus vehicles I've been working on. At some point they stopped making the physical service manuals. It's all online now. I hope this helps you out

What is the type of transmission fluid for 2007 Lexus LX470 please 🙏?

[@TimmyTheToolman]

Check the user manual that came with your SUV. That should have all relevant fluid types and services intervals. - Sean

[@petepoling5199]

If you drain 2qt from the pan and install 2 qts back why all the extra work with terminals and special procedures? I understand when you do 12-13qt you could be adding less due to the hose length of the tool. I don’t understand the Toyota procedure?

[@TimmyTheToolman]

The procedure is to confirm the level is good. If the trans was a bit under-filled to start with, now you still have an under-filled trans after the service. With the older transmissions, you have a dipstick to easily confirm the level is good. It's a little harder with the sealed transmissions, but if you simply get a tool like a scan gauge, you can forego all that crazy stuff the Toyota manual shows you to do to know you're at the operating temp to check the fluid level.

[@Shaun-ze6bt]

The fluid expands when temperature rises, and contracts when cooling, hence the temperature needs to be within range when checking fluid level - and Tim is like me who goes for the center of that range.

[@CristianAPrimoATM]

I've done mine through the front trans. cooler, 1.5qts at the time. Much easier in my opinion. Used valvoline Max Life ATF. 50k miles and no issues.

[@TimmyTheToolman]

I guess disconnecting a hose from the cooler could be a little easier since you're not on your back but I can also see it being messier. With where I disconnected the hose, the ATF is just going to drain directly into the pan I have underneath the vehicle. When disconnecting at the cooler at the front of the vehicle, I can see that being a messy proposition. So, your "Much" easier designation for your method compared to ours doesn't really fly in my opinion. We each had to disconnect a hose and attach a hose. Nothing is hard about that. Anyway, good job doing the flush on your own. Your transmission thanks you. Most people forget about servicing their auto trans.

[@tanimhassan8279]

I have a 2009 ls460 with 200k mileage. The transmission fluid was never changed. Is it ok to drain and fill the transmission fluid?

[@TimmyTheToolman]

I can't guarantee you anything because I don't want you to be pissed at me if something happens. But, if it were me, I'd do the drain and refill. Then I'd do another one in 5k miles and follow it up with a 3rd drain and refill after another 5k miles. This slow process of renewing the fluid is the safest method. I wouldn't opt for a complete flush due to the fluid never being renewed. If a drain and refill causes your transmission to have issues, like the clutches slipping, it was on borrowed time anyways. Good luck!

Do we have to replace transmission oil in 2010 Toyota Camry ke model

[@TimmyTheToolman]

Yes. No fluid lasts forever.

[@DesertGardenPrepper]

It occurred to me that I would like to do the fluid level check before doing any of this. What vehicle was this? How can I find out what transmission I have on my 06 Tundra? How do you know if you should replace the atf filter?

[@TimmyTheToolman]

The vehicle used was a Lexus GX470. Your Tundra has the same transmission. We list all the vehicles that had this transmission in the video description. You can tell if the ATF needs replacing based off service records. If you don't have service records, you can take a look at the color of the fluid. Healthy ATF is pink in color. As it breaks down and deposits gather in the fluid, the fluid gets darker. Dark red is borderline good. If it's brown or black, it's overdue to be renewed. You'll get different suggestions on the interval to do a full renewal or partial renewal. I believe a full renewal should happen every 30k miles. If you want to do just drain and refills of the pan, do them every 10k miles or every other engine oil change.

[@DesertGardenPrepper]

oops, I missed that part of the video description, even though I thought I read the whole write up you did in the first comment below. You are a real hero for showing us all these shop procedures! I loved this one! I bought my first Toyota a little over a month ago, but yet I had watched many, many of your videos, even before purchasing the Tundra. It's a 2006, I purchased from a dealer with about 150K miles. I didn't get any service records. Is it normal that around 40-50 mph, it seems to not want to shift to the next gear. It feels like its holding that gear with rpm's winding out about 3000, with no upshift, unless I keep the pedal going and then it eventually does and seems normal in other situations, as far as I can tell, lol.@@TimmyTheToolman

[@khaithi]

Do you have any clips on transmission filter replacement for this GX 470?

[@TimmyTheToolman]

No, we don't. The transmission filters in these transmissions are a fine mesh strainer and not a paper filter like a lot of American motors vehicles have. If you renew your fluid on a regular basis, that filter will never become clogged and have to be changed. It's only when a transmission is completely abused and the fluid is allowed to become black and build-up sludge deposits that you should consider replacing the filter. But, we do have this video if you really want to go for it, which would be very similar to dropping a pan on any automatic transmission. kzbin.info/www/bejne/qqaqkq2Endp4qq8

I have a 2019 gx 460 coming up to 30000 miles when do I think I should do trans job 50000???

[@TimmyTheToolman]

It depends how you drive it. If you regularly drive in the mountains, I'd do it now. If you only drive in the mountains a little, 50k would be fine. If you never go in the mountains and just cruise down flat roads, you could probably wait as long as 100k. I think even if the rig is driven as a grocery-getter, the longest I would wait to replace the fluid would be 75k. The life of the fluid is related to the temps it's been subjected to. The higher temps you run, the lower the life of the fluid. This is the reason for the suggested intervals based off how much you drive mountain roads. When climbing grades, you will achieve high trans temps. You would also achieve high temps if you tow. I always err on the side of renewing it sooner than it needs to be done. Why? Because fluid renewals are affordable and easy to do. A replacement transmission is very expensive to buy and every expensive to install. Toyota claims their WS ATF is lifetime fluid. That's idiotic. Well, the transmission failed at 200k. I guess that was it's lifetime. All fluids break down. It's smart to maintain your transmission by giving it fresh fluid when it needs it.

[@fate3688]

29:50 my toyota had black oil came out of it, I drop the pan and clean the filter. The filter itself was so dirty. Took about a gallon of gas to see a suitable result. I would have replace the filter right then and there but where I live doesn't have those advance car part shop to get what I want. Have to order what we want from the state or elsewhere

[@TimmyTheToolman]

We should have replaced the filter as well based off how dirty his fluid was, but we didn't have a filter nor the time to drop the pan.

[@Zeczam]

How long does it roughly take for the temperature to get up to range?

[@TimmyTheToolman]

It can depend on the ambient temp you're working in, but I'd say it's not too long, maybe around 10 minutes.

I have a 13 Sequoia i did a pan drain and fill only. I got 5qts out of the pan. Truck was sitting for 2 days before i did it. Is this normal? I see people getting about 3-4 on average

[@TimmyTheToolman]

There seems to be inconsistencies of how much comes out on a drain and refill. The important thing is you do the proper fluid level check procedure we show in the video so you get the level correct after you're done.
