Can Changing your Transmission Fluid Cause Damage?

[@ItsDrillz]

@@chrisfix I clicked on this video SPECIFICALLY to make sure you explained how flushing can cause loss of function in cases with no prior transmission service. You nailed it. Awesome job.

[@guseks8413]

@@ItsDrillz So maybe you can answer a question from me if you know things about transmission. I thought my car shifted abit weird (I have a sealed transmission) so when I had it at my usual shop for service they told me I should get it flushed and they refered me to another shop that had a machine for it, so I did. At the time my car had done about 180200 miles(I know quite abit) and serviced according to the book, and since it is a sealed transmission I don't know if the previous owner had ever changed fluid on it before. Anyway to the problem: Right after they flushed the transmission the car shifted kind of weird when it was warm, say if you drive 10-20 miles highway and then go into city traffic it shifts hard and when accelerating on highway it is like it shifts 1,5 times per shift if that makes sense, first a shift and then another small jump that changes like 200rpm. After like 100 miles of driving it stopped doing that and it shifted super smooth and it was great, but now after another 8000 miles it has started again. When the car is cold it shifts nice and crisp but still smooth. Could it help to change oil again or is it just done and ready for the scrap? Or maybe there is something else one could do? Could they have put the wrong kind of fluid in? Thanks for answers :)

[@ItsDrillz]

@@guseks8413 I don't think there is a way to for me to know the full extent of the condition of the transmission over the internet. As you stated, we also cannot know the previous owner's treatment of it either. This is where I wrote a big long explanation with the possible causes of the issue but I decided instead to just sum it up with recommending you take it back to the shop that did the flush and have them diagnose it. It is much too complicated for me to make a recommendation of a fix without being able to see or test the car. If you'd like the full explanation, reply to this comment and I'd be happy to write it for you but the short answer is to take it to the place that's had the car because they would know more about your car or at least be able to test it and verify the issue. I worked mainly with GM products in the past and don't recommend flushes on cars over 120,000 miles unless they are already losing function. It is too much of a liability to flush it and end up with a slipping transmission.

Hi, I recently purchased honda accord 2009. Transmission works great, but the previous owner (only 1 since 2009) has never changed it, 200k miles on the car.

[@Mijanboy]

@@joshymcdaniel9233 There is a simple answer to that. If the manufacturer claims that the filling in the automatic transmission is for life, you do not need to change the oil. The transmission should last 150,000 km = that's the guarantee of new Mazda cars. 6 years or 150,000 km. This means that the lifetime of the Mazda is 150,000 km. If the transmission dies at 160,000 km, everything is OK = it's only your problem. If you plan to keep the car longer, you must service it accordingly. My Mercedes had 1,603,xxx km when it was taken out of service due to massive body corrosion. The engine has been in the home tractor for 6 years and I gave the automatic transmission to a friend because his had died.

My father worked for a large law enforcement agency for many years. Back in the 70’s the agency did a sting operation where they took an old beater car around to various transmission shops for so called repair. Much of the internal parts of the transmission were marked for identification purposes and to determine if parts had been replaced. The car was driven to the shops with a relatively easy fix, just a vacuum hose was disconnected. Of the 13 shops checked, 8 would be transmission shops committed fraud by selling the undercover officer an alleged transmission rebuild. To this day I still don’t trust transmission shops.

It isn't restricted to trans shops. Many regular mechanics and oil change shops also take advantage of the common driver.

Paul Morphy I completely agree with you. Three years ago I took my 4 wheel drive truck in for some work at a transmission shop. The transfer case on the truck had been completely rebuilt less than 1000 miles earlier. The owner of the transmission shop called me to inform that the fluid inside the case was black in color as if it had never been changed in 200k miles. Knowing the case had just been rebuilt, I called his bluff. Advised him it was just rebuilt and asked him if he believed the rebuild case was failing. The shop owner did a complete 180 and said the fluid didn’t look that bad. Yes, always trying to rip you off.

[@olddavid4]

BD- Do not forget that cold weather affects battery strength, which may contribute to your problem. I also weatherize my car locks by getting a graphite oil and applying it to my keys and run them in and out as well as turn many times to be sure it has gotten to all mechanisms. Also, apply some type of lubricant to the catches of your doors, hood, and trunk. I'm sure M-B has some exotic type that they sell for mass amounts of money, but a good parts guy or girl will have the equal for 10% of the dealer price.

It is a shame since the gear fails after 30000-50000 km and a brand new car will need to change the transmission completely (which I did) after only 3-4 years of modest service. Anyway we were told by the retailer that same problem may occur again in the newly replaced transmission and that there is always the same risk of failure transmission just after the oil change.

Best way to find a good, trustworthy, and honest mechanic is by word of mouth. If you have a friend or someone you know who can vouch for them, that's usually a really good start. Also look at Google or Yelp reviews. Don't let 1 star reviews turn you completely off, though. Sometimes people who don't know anything about cars will complain about prices, or they went in for one service and declined another service the mechanic told them they really needed, but they declined, and then they broke down, and then they blamed the mechanic who tried to warn them. My rule of thumb is to weigh the number of 5 star reviews against the 1 stars. But referrals plus these reviews should land you at a really reliable and honest place more often than not.

He brings the filter and me to the manager and says"ooohh this trans is shot look at the metal in the filter" The manager looks at me and says" let me work up a number for a trans rebuild"." I said OK can I use your phone"? "who are you gonna call"? The police I saw your man take those slivers off the bench press and put them on the filter and I'm gonna have you arrested for fraud".

Many years ago we took our vehicle in for a fluid and filter change. The guy at the shop said it wouldn't help and showed me the little filings in the pan. He wanted me to commit to a rebuild. I couldn't afford it at the time so they just put the old transmission fluid back in and sent me on my way. He said I would be back in a month for a rebuild. My dad convinced me to change the fluid and filter. Man was I ticked off when I pulled the pan off of that transmission and found that they had torn the screen off of the filter and just put the old fluid back in. I didn't know how to do a flush at the time so I just changed the fluid and filter. WOW!!!! All of my shift problems cleared up and the car ran great for as long as we had it. So I always, ALWAYS recommend doing a fluid and filter change a least or a (flush is best in my opinion.) You don't have to pay the big bucks for a flush either. You can just do the fluid and filter change first. Then before you start the engine take off the return hose FROM the transmission cooler going back TO the transmission and direct it to your drain pan. Then start the engine. Your new fluid will push the old fluid out all the way through the system including but not limited to your torque converter and trans cooler. When the fluid coming out of the return hose is clean your system has been almost completely flushed. ALMOST. I don't know what percentage didn't get changed but this is pretty thorough. I do NOT believe the shop in my situation put any metal filings in the pan. There are frequently vary small fibers and filings in the bottom of an oil pan. I am CERTAIN they tore off the screen from the filter! My filter was just a fine mesh screen. I would have turned them in but I figured it would be just my word against theirs. It just makes me wonder how many people they conned and how long it went on.

Chris, this is the most informative video I’ve seem on transmission service wether that be changing or flushing the fluid. As a transmission builder I’m asked these same questions pretty much daily and most of the time the customer is still apprehensive about doing a flush or fluid change. I’ve told customers similarly as you stated basically, if the fluid is darker than a maroon color that I only recommend a fluid change. I advise them to do service as the OEM stated in their owners manual or damage will occur. Your explanation and demonstrations of the fluids, and hard parts is remarkably accurate and commendable as a KZbin DIY’er and your channel is always a good recommendation for every individual DIY’er. If the customers fluid is pink (very rare) unless recently flushed or red then I recommend a fluid flush although not using a trans flush machine. After 20yrs of diagnosing, rebuilding and maintaining thousands of transmissions for my customers. I’ve always flushed the tranny’s via the trans cooler return line at the trans method as well as removing the pan to replace the filter, clean the pan and magnet. This insures the torque converter, valve body assy(s), clutch packs, lubrication circuits, trans cooler and lines are flushed of as much debris (clutch material, varnish & metal or moisture contamination) as humanly possible. The only Transmissions that didn’t work for or that started slipping afterward were transmissions that were well on their way out and in need a rebuild in the first place. Your repeated stating of “follow the OEM owners manual” is by far the best advise you can give a customer. As far as transmissions that use “lifetime fluid” is just that, once the fluid has been heated to the point of viscosity breakdown it is no longer a good viscosity for lubrication and is now only a friction modifier therefore it needs to be replaced. I’ve got literally hundreds of customers that will state that fact after I showed them the condition of their old fluid and the damage and in some cases the carnage it caused.

[@Bumblingdesertdweller]

I have worked in a transmission shop for 30 years. if you service your transmission every 12 to 15 thousand miles with a simple pan drop service it should last indefinite. Transmissions rely very strongly on the viscosity of the fluid, and when it gets old and wears out is when you have problems. as for flushing cars that have not had regular maintenance. ATF is the highest detergent fluid there is at 180 degrees. It tends to break years of sediment that has trapped behind the clutches, behind the apply pistons, and in the crevices of the valve bodies loose all at once. this is why people say that a flesh is not a good idea. if you had regular maintenance on your vehicle you won't need a flush. when the flush machines came out we bought one. I've seen cars drive in the shop. get a full system flush. and then not want to move back out. the new fluid broke all the debris loose that fast. our $7,000 machine now sets in the corner collecting dust. chrisfix gave the right advice when he said regular maintenance. I've always recommended that you change it once a year right before your busy time. just the simple pan drop service and change the filter. that will keep your viscosity of the fluid up to good level.

[@frbird51]

When it comes to transmissions, whether automatic or manual, only use the fluid / lubricant that it calls for in your owner's manual.

[@oldtwinsna8347]

Good points! I do a drain/refill every time I change my engine oil (about 10k with the synthetic) on my Honda.

If you are doing towing or other heavy loads the transmission fluid should be checked more often. Greater force between the gears can make more heat and wear out the transmission fluid at a faster rate.

[@kolbpilot]

Here's my transmission story, GM 4L60E, 205,000 miles when I acquired it. 2 wheel drive, '97 Blazer. It was operating normally when I began the flush, disconnecting the top radiator trans. cooler hose & flushing a gallon at a time by starting the engine & holding a hose against the fitting & filling up a gallon jug. Then, I would add 4 quarts & repeat. The transmission fluid coming out was the brownest I'd ever seen. However, it did not smell burnt & no metal particles in the pan. After I flushed the transmission to where the fluid was pretty again I dropped the pan & then changed the filter. No difference in performance, before or after. That was 45,000 miles ago, I keep the fluid clean & full & all is well.

[@nathanporter256]

One of the worst transmissions to work on. I saw the transmission model and my stomach fell. Just got home from working on mine in my friends shop 😒.

[@kolbpilot]

@@nathanporter256 : That might be, I've never worked on any transmission, manual or automatic. Other than fluid & filter changes. The 4L60E has been rated as one of GM's best by all the articles I've read. The 700R4 not so much, from which it came. But according to the articles GM stuck with it, fixing all the problems areas & turning it in to a reliable transmission. Mine has remained trouble free although it probably is a nightmare once one opens it up.

[@kolbpilot]

@bad Good : I see no need. It's a V8 transmission behind a V6. Two wheel drive, never abused (by me, anyway). The Blazer has a (replaced) radiator in which the transmission cooler is built in. I guess all automatic trans. radiators have that cooler but this one also had an oil cooler as well, which I bypassed but that's another story. I find it not really to be a cooler but more of a transmission warmer in the cold months, which helps as well by getting the ice cold fluid warmed up quicker to operating temperature. I just keep the trans. fluid full & find no running hot issues appear in summer time. It leads an easy life, never has to work hard.

Great and accurate video. One thing that I'd like to add: When choosing a transmission fluid that meets your specific type, the wording is important. If the fluid brand says it "meets the requirements of" your needed type fluid, that is not as safe of a choice as if it says, "Approved". "Approved" means it will be recognized as the correct fluid by the car and transmission manufacturer. Meeting the requirements is just the claim of that oil brand's chemist.

[@fun_ghoul]

Exactly, and since most chemical companies make the right kind for pretty much every trans out there, why take a chance?

[@hamboner2]

Bought a Pontiac Sunfire with one of those “sealed system” automatic trans in 2003. Drove it well over 300,000 miles. Yes, a Pontiac Sunfire. Went to have the trans serviced at 100,000 miles. Tech told me if I hadn’t serviced it yet, I probably shouldn’t bother, so I didn’t. Never had it serviced. It never slipped, nor failed. I sold the car, but after 2 years, and 1000’s of miles, it’s still going strong. Guy said the odometer went out at 410,000 miles, and it uses a quart of oil every 1500 miles, but other than that, no problems! Guess I should’ve kept it. I only got $500 for it.

My transmission started to slip when cold but is ok once warm. The fluid has about 100 000 miles since changed. Not black just a pinky brown. Think a fluid changed may help? Winter sucks, gotta let her run 20 or 30 min to warm up good or wont shift. Just sits there until warm then 0 issues.

Cannot stress enough how important this really is. I've had the extreme pleasure of working for Dodge, Chrysler and Ford in the past before getting into heavy equipment. Don't be cheap about getting your transmission serviced, especially for some heavy duty or import applications. Learn to do it yourself, if you must. I knew a really great transmission guy for each brand I worked for, and let me tell you, they stayed busy. Not because of crappy engineering (that's a very minor issue) but because customers would put it off, they heard from someone else not to, or declined service when it would've been beneficial to do it.

The flushing of the trans when it's old fluid, people thought I was crazy when I told them not to do it - you're going to loosen stuff that is effectively suspended and once it becomes free it's going land somewhere else and is going to clog some little port. He spelled it out perfectly.

[@raymondjiii]

@Jake Parker It comes down to a judgement call of course. I would say, and I've done, that if it is easy to drain the fluid - via a drain plug as opposed to dropping a pan - I would do multiple drains of a course of time. I would check the fluid color after each one. I think you are less likely to disturb "suspended debris" this way and still get fresh fluid in place. The last time I did this I drained about once a week (3 quarts). Yes it will cost you more in terms of buying ATF but I think it's safer.

Although he couldn’t outright say it but if your transmission fluid is black and burnt, the reality is, it’s probably going to be best to just leave it as it is until the transmission completely dies. It just means the transmission is already at the end of its life span and if changing the fluid causing it to slip gears is highly likely. Pretty much if it’s burnt it’s already too late and may be a good idea to prepare to replace/rebuild it soon. The video was excellent advice overall!

Good tuturial, especially change vs flush. One point though. Not all transmission oils are pink. E.g. For ZF 6-speed transmissions the oil is a tan/oat colour, whilst ZF 8-speed transmission oil is green. I once had a Mitzi Shogun/Pajero and the OEM transmission oil was pink. The critical thing is the oil spec. Just because it's labelled ATF doesn't mean it's suitable for your vehicle. Many aftermarket brands claimed to be suitable for the Shogun/Pajero even though they weren't the required spec.

You pretty much nailed it, but I’m still nervous about changing mine. At work, we started doing transmission service on buses (Chevy Express 4500) that were 60k-80k and hadn’t had it done. Drop the pan, changed the filter, put new oil. EVERY ONE of them started slipping and needed new trannies. In fact, we’ve got two guys there that have been wrenching for 20 years, and they both said they don’t change it because every time they’ve done it, they go bad. Now, I know you’re right about the build up and that’s why changing the fluid makes it slip, but it’s a bit nerve wrecking to tempt fate when it’s running well right now.

Now I’m in a 2019 Ford Flex that we love and are staying on strict maintenance schedule. I’m disappointed that I didn’t demand the ecoBoost.

Even though your owner's manual (and likely your dealership) will say, "Sealed transmission -- lifetime fluid," I strongly recommend doing a full pan drop and fluid and filter replacement at least every 60K miles. Same goes for Volvo, Mercedes Benz, BMW, and other cars with ZF automatics.

[@staticjordan42374]

found this out to late. My 06 vw passat is almost at 100000 miles and the tranny is slipping and thumping. when i first got the car i wanted to change the transmission fluid but a mechanic told me that it is a lifetime fluid and does not need changing (was at 78000miles). now im wishing that i changed it

[@lochnessmonstere3042]

Yeah they do. Fluid for my differential was just under $50 per .45l bottle. $150 diff fluid change is painful

[@tigercat0924]

John E I work at a vw dealership and they recommend transmission services every 40-60k, DSG and regular automatic

[@CeceMA05]

I have had an Audi for 14 year but only driven it every summer so I have on 25,000 miles on it. Should I have the trans fluid changed.

[@MrQtip]

Xyv Xyv I agree, I changed the transmission fluid on my 2011 Malibu at 75k miles and it came out black. The manual says it's a lifetime fluid and it was to be changed at 100k. Three drain and fills brought it back to good condition and I will be doing a simple drain and fill every 25k. Cheap insurance IMO.

383 dislikes are from crook shop owners who scares you that your engine is about to blow and you need a coolant flush, an engine rebuild and a brand new seat belt!

[@CoolKoon]

Actually when your car starts eating oil like crazy, an engine rebuild (well, sealer ring replacement, which involves taking out and disassembling the whole engine block) IS your only option.....

[@goldenmanuever1176]

"brand new seat belt" LMAO!

[@banno6938]

Or fix the oil leak.

[@yu-gi-ohconcajones2509]

B Anno fixing an oil leak is cheaper than topping of your oil like a dumb fuck

[@banno6938]

YUGI Sometimes it's not depending on the car & the price of oil. Some require the engine to be pulled to change a rear seal or oil pan gasket.

Here is a huge tip for transmissions. Older transmissions that don't have the fluid changed will start to clog the filter. It is said NOT to flush. But, here is a little flush. Get the transmission warmed up for 20 minutes. Park it where you want to work on it. Now shift it to reverse for 5 seconds. Shift to park and immediately turn off the engine. You have just backflushed the filter a bit into the sump. Now empty the sump carefully measuring how much was removed. Pour in the exact amount of THE SPECIFIED ATF or try this Lucas product. Seal it up and do it again in another 50,000 miles. If you have a decent car and you drive sanely, your transmission should outlast other components. I found this out with a 1998 Jeep Cherokee that I had the transmission not shifting well in forward speeds after running for a while. I noticed after putting in reverse, the transmission did well for a while. I had it professionally flushed. There is a LOT on the internet NOT to do this! I was lucky and the transmission worked like new.

[@thetapper61]

Let drained fluid cool to get same level as new fluid as warm fluid will show as more then really there.

[@enriquefontanez3455]

This guy really knows his stuff. Thanks for the tutoring.

[@chrisfix]

Thanks a lot!

[@thurm101]

Love your passion for detail. I was once told that by a old mechanic, "Don't change your transmission fluid if you haven't done it at the 120,000 miles".

[@chrisfix]

+thurm101 thanks man. I like to go by fluid color because if it's still ponk, you should be good!

[@amishdinkledork]

+ChrisFix My fluid is ponk colored too xD

[@SoloAtlantis]

+ChrisFix Fluid colour is an excellent way to check the condition in an Auto trans, just don't follow the same logic for all gear boxes such as differentials, gear lube have static additive supplements that cling to gears, so you could drain and refill your rear diff drive around the block a few times and the fluid will look dark again. so as a rule go by mileage recs from the owners manual in the best case scenario.

[@MetroDET2011]

Never changed it once. 100,000 miles ford focus. Pink.

[@applepoop10]

+MetroDET2011 Depends on how you drive and how hot the fluid gets.

[@honestnewsnet]

You can tell this guy is not just reading from a book or reading some information. He knows what he’s talking about. Makes 100% difference.

[@demolitionman8768]

Chris fix.. you're the man! you sound and look young yet you have so much knowledge in car mechanics... i watch your videos every time I want to work on my car it saves me money but you my friend give me confidence! thanks!
