How to save $400 by Doing Lexus Auto Transmission Drain And Fill Yourself | DIY RCF Drain&Fill Guide

[@Alex-lh8pm]

Good Guide. Barry knows what he's doing. Did the same thing on my IS F

[@thehuangbros]

Thanks Alex!!! Im happy I was able to help you because that helped verify my technique to myself.

[@dugahole55]

Informative video! Good explanation of procedure, I have ISF and the Lexus ISF repair manual. I few additional details for a "Fill Transmission Pan with fluid. Spec says it should take 3.4 L or 3.59 US qts. Toyota makes it possible to check fluid levels without Techstream, this may be similar for other vehicles, but this is what my manual states; To check fluid temp without techstream, wire jump between pin 4 and 13 on OBD port (DLC3). Turn off all electrical items, start car, move shift lever between P and M return to P. Now shift between N and D rapidly for 6 seconds, P indicator will turn off when fluid temperature mode is detected. Put car in P, remove jump wire, while car is still running, the P light will turn on at 95F and blink at 42 F. With engine idling and between noted temp, remove overflow plug, catch fluid that comes out, or add fluid until it comes out. Transmission is at correct fluid level, reinstall plugs.

[@dekkerlundquist5938]

Yes, this is the correct procedure.

[@markmoosai]

This is not entirely correct for the GSF and RCF. Replace P with D will cycling through the gears. The D indicator will turn on once it's up to temp. So basically when you going back and forth from D to N. Once correct temp the D light will come on when the car is in neutral. I just did a video I can post it if anyone needs it.

[@lakay99]

Thanks Barry! Very helpful! I'll do this when my RC350 hits 40K, together with spark plugs, front and rear differential. Very informative video. Aren't you planning on dropping the tranny oil pan completely? That would also give you a chance to replace the filter and collect the metal shavings on the pan magnets.

[@thehuangbros]

Thatll be another video

[@dandeekarlsoriano1581]

i recommend doing it on a cold fluid in the morning, first is to make sure that the fluid that suppose to be in the pan are all in there, next is that atf that are in the normal operating temperature are already expanded, atf tends to expand when its in the normal operating temp, thats why when you drain your atf while still hot you took 3 quarts rather than 2quarts when its cold. those 3 quarts that you took will became 2 quarts when it started to cold. then the bad part is that you put 3 quarts of cold new atf back in in which it makes your atf level inside your transmission 1 quart more, so it ends up you over fill your transmission with fluid that is technically bad for your transmission. you would put cold fresh new atf that you buy on the store which is still not on normal operating tempt (fluid that are not yet expanded) . youre not putting hot new atf in (fluiud that are already expanded). so for me draining it on a cold engine usually int he morning is far more safer, fluid level wise than doing it on a hot engine. this is just my opinion.

[@drivewayhero]

Theres no way two quarts atf expands to 3 quarts when hot. Show a video showing this miracle. Should be easy to do

I recommend driving at least 1k miles before you just do another drain and fill. That way the fluid can mix so you make some use of the newer fluid or else it would just be drained

Great video man!!! Where is the overflow bolt located if you are using techstream

[@thehuangbros]

Hey Rafal, the check valve is at 3:52 in video. Its on the side.

[@thehuangbros]

So techstream is a software toyota uses to visually see the temps and other properties of the car. It just tells you once you hit 120-130F that it is time to unbolt check valve to let overflow come out to a trickle. Thats really all.

[@hirpmvtec]

Hi Barry hopefully you check your comments still ! I am going to be doing all the fluid changes on my 2017 RCF. Regarding the trans, is it really necessary to measure the trans temp or is it enough to do the drain and fill right after driving it say for 30 minutes ? I bought an obd2 device and fusion app but i have to pay more now if I want the enhanced features like viewing the temps. Thanks

[@thehuangbros]

It is best to open the check valve at 114F. Then once it starts trickling, close it. If you dont want to do it this way, just put back in what came out and then add about 1/4 qt. A little over is ok, just not a lot.

[@hirpmvtec]

@@thehuangbros thanks for the reply, just a bit confused, if after you open the check valve and close it when it starts trickling, at one point do you add new fluid? And is it the same amount that comes out? What are you using for measuring the temp? Thanks !

[@thehuangbros]

@@hirpmvtec im using a handheld laser one and then there is also my obdfusion app. After you drain, add the replacement oil, then do the trickling from check valve.

[@vuahung33]

Hey Barry,did you have to replace the ATF filter and at what mileage when you change your. My RCF just turns 50,000 miles and I'm planning to do mine. Thanks

[@thehuangbros]

I did not replace the trans filter yet but on this next one I plan to.

[@hybridparts3169]

How will tech stream help

[@thehuangbros]

So toyota techstream will allow you to monitor the transmission’s actual temperature so that you can then open the check valve, which i did not show, to allow the excess to overflow out of the valve. It will overflow at I believe ~130F and once it comes to a trickle, it will be the correct amount since ATF fluid expands with heat. Non F performance cars I believe are a little lower like 113-117F.

[@Magicstockton]

Appreciate you my guy.

[@thehuangbros]

Thanks!

[@vlmoua]

Fluid still looks good, but never hurts to do it

[@thehuangbros]

So I kinda forgot during the filming that its actually been 17k miles. It was natural for me to say 30k because that is ideally when to do this for Lexus. When I did do it at the 50k, 60k, 66k mark on other cars, omg was it dark.

[@tonyramirez7092]

I’m thinking of buying a 2015 RCF with 84k miles. Would you drain and fill the transmission fluid assuming it’s never been changed? I’d hate to do it and risk slippage ​​⁠

[@thehuangbros]

No slippage. I would do it

[@tropicalspeedbmw]

Make sure fluid temp going in IS the same as temp of fluids coming out.

Good tip

[@vuahung33]

How do you do that? and what you used to measure the temp? Thanks

[@tropicalspeedbmw]

@@vuahung33 easy. Drain the fluid when it's stone cold. If you absolutely have to drain with the fluid hot, get a thermometer and record the fluid temp of the drained fluid THEN bring the fresh fluid ( up to / close to ) to the same temp. Thanks

In the begging of the video for the transmission fluid you had both the multi-vehicle (red cap) and fuel efficient (blue cap) fluid. Would it matter if I used the red cap or the blue cap fluid? Let’s say it goes into a Lexus IS 250

[@thehuangbros]

Good questions. Use the fuel efficient blue cap one. That is what amsoil recommends for lexus. But i have used red cap also for lexus and no issues

[@theoracle2877]

Hi , when do you check the level is correct as it may have been low before hand? Is there a definitive correct level I mean!

[@thehuangbros]

Ive done this exact procedure 5x on 2 different lexus rcf. Its been the same amount that comes out in this video every time. To check the level, turn car on, let trans warm up to 107-117F and then open the check valve and let it drain until it trickles. Then recap and done. But again, ive been successful 5x with exactly same amount every time.

[@sensay813]

Great video you should have shown the Jack points and how to lift the car in more detail. Some people are going to be risking thier life if they don't have this car lifted correctly. Use wood under the tire is a great way to stay safe doing this

[@patricknguyen632]

Hey I’ve heard that there is a overflow nut, does that do anything to help you from overfill or under fill? Thanks!

How is the Lexus RC with the Amsoil Fuel Efficient Transmission Fluid. I am thinking on doing this to my Tacoma and making the switch from Toyota WS to Amsoil. Obviously you know of all the scarce Toyota creates on having customer's believe Toyota WS is the only fluid you can use on Toyota/Lexus transmission.

[@thehuangbros]

Its been great. The downshifts are still fast and more reactive after draining the metallic and possible gunk. The shifts are smooth as long as you put in what came out.

@@damiankrukiel1981 no worries

[@Pau1ywog5]

Stick to Toyota ATF WS. When you drain these systems, you do not get all the fluid out. Not even close. So you'll just end up mixing fluids. If that's ok with you, fine, but not sure it's worth the risk. Toyota's version is readily available on the internet and at the dealer via the parts counter. Also, in this video, it's unclear if the volumes of fluid were checked at the same temp. If not, you'll get an incorrect reading. Better to do this using the built-in fluid temperature check mode that other commenters here have mentioned.

[@rayking3406]

Do you recommend using amsoil on for transmission & rear differential on is250 2014 & on a LS460 08? Been using valvoline

[@rayking3406]

I did a transmission service on my is250 at 124,000 miles & was in traffic & came to a hard brake & felt a jerk when came to complete stop on the transmission. Any recommendations?

[@rayking3406]

Whatever recommendations help, so I know what’s the best to use next time when I need to service the transmission & rear differential. I know Lexus react differently to different types of fluids depending on how thick & the brand….

[@kevinherndon4509]

Quick question, I lost transmission fluid because the line burst on the way to the transmission cooler. How would I be able to know how much transmission fluid I need to put back in? Also my car has 150,000 miles and I don’t think the transmission has ever been serviced so I am scared to do a complete flush of the system

[@thehuangbros]

Ouch that is a tough one since youre past 100k miles which you should not do a flush if never done once before 100k. But youre in luck, add atf fluid the way you see it in this video. Let car idle and measure transmission pan to 113-130 deg. Once its in that range open the transmission pan check valve that requires a allen key. In that temp, once you open the check valve, the excess should flow out then come to a oozing stream and not a trickle. But if you see no stream, then that means you need to add more atf.

My car had 95k miles on it when I bought it and transmission fluid never was changed. Should I do 2 or 3 drain and fills to get old fluid out ?thx

[@thehuangbros]

Hi. You are on the borderline. So at 100k miles or more, it is not recommended to do a trans fluid drain and fill because in that old fluid, the metallic can be what is causing your transmission to not slip. However, If you do one drain and fill, you will still have old fluid in the system which will have metallic still so it would be okay. If I were in your situation, I would do 1 drain and fill and drive for 10k miles to see what it is like, then do another then monitor again to ensure you don't get transmission slippage. I hope that makes sense. Let me know if I need to explain more.

@@thehuangbros 08 LS 460 when I got it, it was reving over 3k rpm between 20 to 35 mph alots. I had local mechanic drop pan replace filter gasket and fill.

My receipt I noticed the only charged me for 5 quartz so I'm sure they didn't flush but just did a drain and fill. Car was shifting just fine after for 1500 miles or so. Last week I had to drop off at Lexus dealer to get all my interior trim replaced for free, I asked them to check battery and transmission fluid level. Trim was over 10k that I got free. When I got car back home now not alot but every now and then it will reve to 3k not often. I hope they didn't drain some fluid but idk.

Thx for ur help this is by far best car I've ever owned and I just want to get it right 👍

Glad you are loving your car. So it sounds like you do have transmission slippage that is why it revs high. So because there has been drain and fills, multiple times it sounds, you may need to add the additive for non slip stuff from Lucas like you said.
