Transmission Fluid Specifications: Can you trust the Labels?

[@truth4reel]

I love professor Kelly and have been a subscriber for years, but as far the Valvoline max Life ATF goes, that fluid is a life saver. I'm a professional technician and have used that fluid on Fords, GM, Mazda, Honda... I have never had any issues whatsoever. For the 2012 Mazda 3 Skyactiv I had the trans. fluid cost 25 bucks a quart. I filled it up with Max life Atf after having removed the valve body for TCM replacement. That was at 69340 miles and had no issues until I sold the vehicle at over 90K miles (with a lot of LIFT and UBER miles). Zero issues.

I’ve been using Valvoline Maxlife in Toyota(WS,T-IV) Honda(Z1, DW-1), Ford(Merc), GM(Dex) and a few other types as replacements for years with absolutely no problem and according to owners(friends and family) they can’t tell the difference or better shifting. It’s in all my cars and families cars. It’s so affordable that they don’t skip the service intervals. One of my cars has 150k on since I started using Maxlife on it. I’ve used Valvoline CVT fluid in those problematic Nissans and never had one fail. They seem to know what they’re doing in my experience. I do like your channel and has good valuable content thank you for taking time to make it.

@@WeberAuto Dear Prof. Do you have an opinion about AISIN ATF 6+? www.be.aisin-europe.com/en-gb/products/autofluids/atf Aisin claims it fits Toyota WS, Honda, Dexron VI, and some ZF transmission. It makes me believe that there is indeed certain tollerance and high quality additives that are above all standards or requirements to be considered as universal ATF. It is the same price as TOYOTA WS in most countries, so pricewise makes sense.

[@davidmiller9485]

@@rondhole I have no idea what the professor will say however, "Universal" anything usually isn't. You can't make a fluid that is all things to everything. I own a Gen 2 Prius.

[@xr500t]

I'm loving the history of the fluids.....thought, at 31:30 including the Castrol description when you were shopping Walmart, the Valvoline Maxlife is deemed misleading. That may be so, but, I started alternating Stock Honda atf with Castrol, and then Valvoline, due to cost. The switch was made at 25K on a Honda Odyssey, and an Accord. As of today, the Accord has 370k mi and the Odyssey (with the notoriously bad trans) has 270k. Valvoline has done the job for me at a price that is reasonable. As an aside, the manual indicates that an alternate (can't remember which) can be used temporarily.

[@administratorsowners1508]

[@gooseno6090]

I too have watched with great interest Prof Kelly's videos on ATF. He laughs off multi-purpose fluids from majors like Castrol and Valvoline Max Life. I'm trying to figure just how many traits ATF has to have to warrant do many different specs. Viscosity improvers, anti wear, oxidation inhibitors, viscosity specs, frictional specs for clutches and detergents. Not a tremendous number of items compared to the number of different specs. I can see how these specs might overlap each other and work in multiple units. I personally talked to Valvoline's tech people and they said they have extensively tested their product for each individual recommended manufacturer. Being the oldest oil company in the world and with an impeccable reputation, I would tend to trust Valvoline's word. Plus, I've watched numerous videos on KZbin Where Max Life was tested by Blackstone Lab's and others after long runs in cars and trucks, with stellar results. Plus I've used it myself with zero problems. So, in (some) instances, like Valvoline, I will have to disagree with him.

[@richardborge8541]

@@gooseno6090 I agree with you. Seems ridiculous that every manufacturer has their own fluid label and color. It implies that each has its own mysterious "secret sauce" that no one else could possibly reproduce. Car manufacturers frequently develop engines and transmissions together which results in homogeneity across the industry (Mazda Skyactive transmission was based on a Toyota design. Ford developed transmissions for Jaguar etc). Imagine if each car company had its own proprietary motor oil requirements...heaven forbid you don't use Mazda blue oil in your Mazda engine. As consumers, we have been done a disservice that ATF has not been regulated like motor oil.

[@ricktotty2283]

In my opinion it’s the manufactures are the ones that are selling snake oil. I work for a very large fleet operation. We use a pennzoil product that’ is around 5 dollars a quart instead Mercedes product that is 17 dollars a quart. We have worked closely with both manufacturer and vender to test these products. Although Mercedes does not like the use of aftermarket ATF they do not refuse to pay any warranty claims. Many of the sprinters have been driven three or 400,000 miles with no issues. I received 19 2002 sprinter and transfused all their transmission fluid every 50,000 miles until all 19 were retired without a single failure. I love your videos I just the don’t think that the manufacturers are more honest.

[@WeberAuto]

Thanks for your feedback. Obviously there are many variables among the different manufacturers and transmissions. I have not researched Mercedes fluid specifications yet. As stated in the video, the Magnuson-Moss warranty act prohibits manufacturers from denying valid warranty claims with unlicensed fluids. The fact that you are changing the fluid every 50,000 miles helps extend the life of the transmission as long as the fluid level is set correctly each time. I do not think the manufacturers are being dishonest, but the price of some of their licensed products seems high.

[@simonm7776]

I do trust Valvoline. They are a highly respected oil company. At 35.16 they are clear with the consumer as to what their ATF is. What more can you ask for?

[@WalkerKlondyke]

First off, I love this channel. Been in the business for about 15yrs and still am excited to learn from your vids. So, I've got a shop that specializes in Honda's. I always use Honda DW-1 ATF as well as all the other Honda Genuine fluids when performing standard maintenance. However, my transmission guy, who I've used for years for all those Odyssey and Accord transmission rebuilds, laughed at me when he saw me using the Honda DW-1. He explained that every rebuilt transmission I've gotten back from him was filled with the cheap, generic fluid from Advance Auto Parts. I was surprised, and initially concerned, but I've got countless rebuilt transmissions out on the road, many with over 100k miles on them. They're lasting at least as long as the original Honda builds. Also, I've been using the Valvoline MaxLife in my own Pilot for a few years as a test case. I'm not saying you're wrong in your analysis of the makeup of these aftermarket fluids, but, real world experience is suggesting that there's no practical difference. I'm just curious as to know how to account for the discrepancy between what I'd expect to see and what I actually see. Is it possible that the cheap stuff is still good enough?

[@WeberAuto]

Excellent feedback and comments. I am not saying the Maxlife is always a worse choice than a factory licensed fluid. I am saying that the general public has no idea of what to purchase, so they rely on the front package labeling and claims. Purchasing a licensed fluid guarantees that the fluid meets ALL of the manufacturer specifications, not just some of them. The fact that the base oil of Maxlife is Full Synthetic (Which could be a Group 3, 3+, or 4 base oil) means that it will automatically perform better in some aspects of transmission operation than a transmission fluid with a Group 1 or 2 base oil. But as you saw, there were 36 specifications in the GM document and only 8 in the Valvoline information sheet. The additive package and verification of performance of a licensed product is hard to beat. Remember, unlicensed fluids with the wrong formulation may not necessarily cause an immediate problem, the problem may be a shorter lifespan of the transmission. At that point, who will be able to prove the fluid caused it? You could pour 0W-20 motor oil in a transmission and it may last for a long time, but eventually something will fail prematurely or perform incorrectly. Thanks again!

[@slscamg]

Friendly Robot sometime I wonder if it’s the mixing of fluids that causes a problem. A lot of transmissions are just a drain and fill so you’re mixing after market fluid with the factory fill. This video has great timing as I just had an issue with a VW 09G that had a dent in the trans pan that was replaced. The shop put in Maxlife and a couple thousand miles later it’s slipping and is shot. VW dealer confirmed they’ve seen this before. Keep in mind there are only 60k miles on the car. Getting back to your point I’m wondering if it’s more of a reaction then the fluid not working those rebuilt transmissions had a full full of the aftermarket fluid and it wasn’t mixed with the Honda fluid. Just my thought for the day.

[@WeberAuto]

Good point! Fluid mixing has to be an issue.

[@WalkerKlondyke]

WeberAuto great points, it occurred to me that at least some of those rebuilt transactions probably came back to me at some point for a fluid drain/fill service. I would have used the Honda Genuine DW1 and typically on the Ody’s I’ll and Accords with known trans issues I’ll do the full 3X Drain/fill. So, maybe they’re ending up with the good stuff after all. But I’m certain there are many out there still running on the cheap stuff, or the customer has gone to a Jiffy Lube for convenience or to save money. I suppose, once most cars get into the 250K-300Kmi. range, there are plenty of other factors which will put it in the scrap yard before the rebuilt trans gives up the ghost again. This is, of course, all just anecdotal evidence. And nothing trumps actual data. Thanks again, particularly for your series on hybrids!

This is an excellent review of transmission fluid specs and how to read the label correctly on transmission fluid products for sale to the consumer. I have a 2002 Toyota Tacoma V6 Double-Cab 4x4, and per my Toyota owner's manual and Toyota factor repair manual, my Aisin automatic transmission Model No. 30-40LE requires Dexron III automatic transmission fluid. My local Toyota dealer sold me Toyota auto transmission fluid T-IV and insisted it was backward compatible for Dexron III. Toyota T-IV is not backward compatible with Dexron III. This led me to search for the correct automatic transmission fluid for my Tacoma. The most recommended and popular automatic transmission fluid is Valvoline's Max LIfe in non or synthetic versions on many Toyota and Tacoma forums. When you read the label on those ATF products, they are NOT GM licensed and not GM-approved to be backward compatible with Dexron III, as explained by Professor John D. Kelly. Dexron VI is backward compatible with Dexron III. Valvoline does sell a GM-approved and GM license Dexron VI automatic transmission fluid, and so do other companies.

[@RockandrollNegro]

Good luck with that. Amsoil very rarely licenses OEM specs or pays the approval fees, therefore if you have catastrophic drivetrain failure under warranty and they can prove you used an unlicensed fluid like Amsoil or Maxlife, they legally are not obligated to pay out. These fluid manufacturers like to tout the Magnuson-Moss Ruling like it's some magical shield of protection that allows you to run any fluid you want, but the courts say otherwise. Oh, and no need to run Amsoil. 50 years ago it was better than everything that wasn't Mobil 1, but nowadays it's just a very basic oil that performs as well as Supertech Full Syn. Save the extra money and weird cult-like pyramid scheme dealer program and just buy any decent synthetic oil that is approved by the vehicle manufacturer. They're literally all pretty much the same now, barring weird older spec fluids specific to older/exotic engines.

While I respect what you did here I still have issues. It's all nice and scary now to think of using anything but a OEM fluid because other makers like say Amsoil don't get the approval from the OEM's. It's a cost issue for one.and business folks like Amsoil didn't buy into this, they let their rep. speak for it's self. I used Amsoil in a lot of cars in the engine, transmission (manual and auto) and got great results. OEM's love to scare us to use only theirs at a very high price for oil they don't make in the first place. And a OEM like Toyota, their oils isn't all that good anyway and you need to change it around 40k miles. They say 60K or so but to OEM's as long as it holds out before your warrenty runs out they are happy as they can get. Buying OEM is crap and there is a good reason that act was done to keep car owners being forced to use only their products or void getting their cars fixed. Another thing, while there are many others who make it a good few of them aren't going to sell crap because even though they got a out (maybe, maybe not) if their oils damage engines and transmissions it will still get out to people that they sell a defective product and I'm sure they do a lot of testing and make sure they aren't putting out a harmful product. It's really very easy to tell if a Trans. or Engine is oil damaged and not due to other reasons. Even a back yard mech. can tell if it's a oil issue if they tear it apart and have a look. or even just testing the oil after some use will tell you enough. It's like that time when Arco came out with a new oil that damaged engines and got pulled off the market and they had to buy a lot of folks new engines. I guess they found that graphite wasn't all that good after all. There was a lot of really pissed off people and that just isn't good for business. Would you really use OEM only given the choice ???

The same issue goes on in the ag and industrial sector as well. Fluids sold as "recommended for xyz" and they don't actually meet the specifications. Most are sold as universal tractor fluid (utf) or universal hydraulic fluid (uhf). They show failure on systems with clutches (wet traction clutches and transmission clutch packs) and wet brakes. Most common issues are delamination, slippage, and heat issues, and some side effects of plugged filters and screens, and pump failures. A basic system with nothing but a simple pump and a few gears will usually get by, but more complex systems have a high chance of failure. Lot of lawsuits out there about it.

I use Valvoline Maxlife in all of my cars, I use them for towing my tandem fiberglass boat with a 5.7 merc in my sequoia, I have over 200k miles and using maxlife, shifts like new. I understand what he's trying to say in the video, and I understand it from a theoretical point of view, but he has no idea of Maxlife is better or worse because he never tested it against say...Toyota WS fluid. I'm not saying his research isn't valuable, I'm just saying he's very much like other academics in that all of the work is done at the screen and with paper, not in the real world. I also use Maxlife in my Lexus RX350, 2010 Toyota Corolla, Nissan Xterra (my fathers) which has over 200k miles, and 100k miles running the RED MAXLIFE he shows here in the video. Shifts like a dream... Testing/evaluating results in the real world is the only thing I care about anymore (after getting to a base level from specifications). If I had put Maxlife in and had trouble, I'd buy everything he's saying, but I've read story after story on forums of all different manufacturers and had my own experience with Maxlife, it seems to be one of the best fluids out there IN USE. I'm sure there are bad fluids out there, but specifically Maxlife doesn't seem like one of them. I'm surprised he chose it for such a large segment to pick on them in a way, because everyone I know that uses it hasn't had a single issue, and in some cases it has been better than OEM. I'm not discrediting his paper/screen based and academic analysis, however it needs to be backed up by real world testing and fluid analysis after use. Of course this would be very time consuming for anyone to do, and not really feasible (I don't expect him to do it), but I also don't expect him to trash brands without fully testing.

Thanks for watching

[@oleglishchenko4922]

Have you used Valvoline maxlife in newer Toyota/Lexus that call for WS type of ATF? If yes, how that went?

[@jlrosine]

@@oleglishchenko4922 Yes, my Toyota Sequoia 5.7L with the 6spd transmission (requires WS). I have 204k miles and tow with it, it drives like new. My wife's Lexus RX350 (2011) with 6spd requires WS, a 2010 Toyota Corolla. All require WS, no issues and I've done quite a bit of extensive research in forums, folks with hundreds of thousands of miles on Maxlife. My father has been using Maxlife in his 2009 Nissan Xterra (same 5spd they put in the Armada/Titan) for about 100k miles, still going strong at around 200k.

[@henrymaradiaga9069]

Well, thank you for sharing this info, Iwas about ti change my toyota Hilux 2012 with maxlife but I stopped for this video; after reading your experiances I will continúe this the process. It is really diffucult to find the real product here where I live in Honduras central America so Maxlife is the only option. Thanks again for your good info.

[@runnerxa]

I will chime in with my real world use of the Valvoline MaxLife ATF. I also have been using Valvoline Maxlife on my Toyota/Lexus vehicles that call for Toyota WS ATF for a long time. Two of the vehicles (4Runner and GX) have over 220k on them and one (LX) just passed 150k. All 3 shift smooth and I service the ATF every 60k (not lifetime as Toyota lead you to believe). The 4Runner is supercharged with upgraded valve body in the transmission and have been serviced using Valvoline MaxLife ATF since I supercharged it at 80k. The GX and LX have tons of towing miles on it using Valvoline MaxLife ATF vice Toyota WS. All 3 vehicles have their share of off-roading from desert, snow, sand dunes, and mudding in the west coast. I also monitor the ATF temps through the OBD ports and added/upgraded stock transmission coolers on them. Someone should compare ATF oil analysis in the same type of vehicle with Toyota WS in one and Valvoline MaxLife ATF (or any other brand) in the other after 60k of driving. The first time I change out the Toyota WS fluid that came out of my GX and LX, it stank and is a very dark fluid. The MaxLife ATF after 60k drain was purplish dark but not black. It is one of the best price to performance ATF available to consumers. I might even say better than OEM Toyota WS (I am no scientist and can't prove it except through real world usage on my vehicles). If you want the best, I suppose you could pony up for the Amsoil ATF.

[@Fred-F4]

Great video! Why manufacturers e.g. Honda, do not publish their fluid specs e.g. DW1? There should be a law forcing them to do that

[@sat_sonic]

the Honda forums definitely are divided. Watching this video and doing some quick research DW1 is simply not licensed to anyone. What would be interesting would be to see the ASTM test results for Valvoline multi vehicle max life versus DW1.

[@Splitthatpie]

This is the transmission fluid that I used in my Jeep Cherokee with a nine speed. I changed it at 170,000 miles because my transmission I was told that was going out in my transmission has never run better in my life. Don’t be afraid to change your fluid, change it and don’t be afraid to use my life because it’s far better than anything I’ve ever seen.

[@zech007]

Should kinematic viscosity indexes be closely adhered regarding per manufactures requirements when choosing universal ATF? With newer transmission coming off the lines with lower viscosity to meet reduction in friction and CO2 and having major oil companies creating ATF to cover a wide spectrum of vehicles. I see a concern of viscosity not meeting to par with discontinued/post manufactured modern transmission manufactures ( ZF 6hp 5hp, MB 722.6, ect) that uses special spec with specific parameters, and making the matter more pressing is recommending manufactures posted approval on certain/specific universal ATF bottles. I'm aware that there is OEM fluids that can be purchased from the dealership but with most DIY, or some (not all) workshops who is going to changed/service the transmission aren't going to spend that significant amount of money in specific fluids. PS excellent presentation, i have been advocating correct spec fluid to my friends and colleagues who inquires my assistance with their vehicle problems/concerns, and most of them are surprise that all fluids are not the same. Take care professor!

When your product is on top which Valvoline Max Life is esp. the Multi Vehicle everybody & their brother is trying too knock you of the top of the mountain.

[@blautens]

Having been burned on Honda and Mazda trans issues, with at least 2 problems clearly related to improper fluid changes on those, I do all fluid changes myself now and don't even buy licensed products but use genuine OEM fluids instead (except for DEX VI on rare occasion, mostly because I use so much). Often the price is super close to licensed products. And Toyota's lifetime fluid idea is ridiculous. I clearly resolved shifting problems on a 113k mile Lexus RX 5 speed auto with 3 drain and fills with genuine Toyota T-IV.

[@amazoidal]

After losing the PSD in my 2008 Prius at 90k, I am now using REDLINE D6 in my 3 Prii. My "shifts" are smoother and regen noise is less. The ATF is about $50 a gallon. Now I can buy WS for 10-15 a quart but many groups on You Tube have had Blackstone test WS and it fails fairly fast with heat. It is definitely not "lifetime". The stuff looks like black water after 30k. I can buy a Valvoline or other big-name "Synthetic" ATF for about $25 a gallon but I bet it's just Group 3. I think the PAO is the price difference between that Castrol and the REDLINE. Do really think the OEM Fluids are really Group 4? Their "Synthetic" engine oil isn't.

[@WeberAuto]

Thanks for your feedback. The Prius maintenance guide tells you to change the WS fluid every 60,000 miles if driven in desert heat or towing (Both are high heat producers). The primary job of the ATF in a Toyota hybrid transaxle is to remove heat from the stators. PSD lubrication is obviously a priority as well.

[@Mr.Beastforpresident]

Stanny1 Do you really think Toyota is smart enough to engineer a reliable car but not smart enough to use quality OEM Fluid?

[@amazoidal]

Go to your Toyota dealer or your local quick-change oil place and ask them if they have a Group 4 oil. See the look on their face. I like to ask the counter people at O"Riellys the same question. I met a Pennzoil rep a couple years ago and he thought I was talking Greek. Or he was playing dumb. But I think Toyota went to Aisan (who builds Toy Transmissions)and got some extra fluid to sell. Aisan set the specs. It's like the Wolf watching the hen house. Look up some Toyota blogs and you'll see the discussions on WS. Luckily, the Prius is not hard on fluid. But towing with a Tundra? You are in trouble!

[@Mr.Beastforpresident]

Stanny1 There 2 guys with 1 million miles on a Tundra and I can assure you with certainty they did NOT use Group 4 oil. On top of that, I put 541,000+ miles 13,000+ Engine hours on a 2007 Chevy 2500 with Orginal Engine & Transmission and never used Group 4 oils in neither. Furthermore, the guy who has the Guinness Book of World Records record for the most miles put on a vehicle at 3 Million Miles on original engine hasn’t used Group 4 oil. There’s no Substitute for experience, knowledge & experience are two different things. The only thing worse than ‘ no ‘ information is the ‘ wrong ‘ information. Don’t buy into the Kool-Aid. Buy into the facts. To each their own but as the old saying goes... A fool and their money will soon part

[@amazoidal]

Maybe Group 2 oil? That's a lot of years. Did these engines race, tow, or have a turbo? Then you won't need Group 4. Walmart Super-Syn is what I use in my 3 Prii. About $17.00 for 5 quarts. But now that Costco has Warren Syn in their Kirkland Synthetic (10 quarts are about $30), I'm loading up at Costco. This proves that when Castrol took the PAO out of Syntec, they could sell a $3.00 a quart Group 3 for Group 4 prices. All the oil companies except 3 in the U.S. have done this and still charge $5-9 for a quart. Costco is proving that Group 3 is really cheap to make. If Costco could get rid of the retail packaging and sell in bulk, I would drop below $3.00 a quart. Costco beats Walmart for I bet the same Warren SN+ Syn. So why would your old-timer record setters use anything else? They could probably get even more life out of their vehicles.

A video with your expertise thoughts on Aisin dw1, Idemitsu H and Honda dw1 would be interesting. You'd think if anybody had the best it would be Aisin's dw1. The convenience of purchasing Idemitsu H is hard to resist. All and all better safe than sorry so it's OEM dw1 for me.

[@mrflamewars]

Maxlife ATF works pretty well in my 387,000 mile $700 beater 1993 Honda Accord - stopped it from being so insanely violently slammy. This is an "eff it" kind of a car because I bought it with a burned up Transmission control unit to begin with though. It came with an OKI made 28100-PX0-732-3EX and I replaced it with a Denshigiken made 28100-PX4-731-3EX as all the reading I did said that the numbers don't have to be exact in a car this old. The OKI Made transmission computers always burn up in one corner and the Denshigiken ones don't.

@@WeberAuto The specification in the owners manual (came with it, with the original owners name written in the front even, spent it's whole life in the south so it's not rusted away) says it calls for Dexron II so I guess it's not hard to make it happy. The Honda Box is, as I'm sure you're aware, an odd duck. More like an Automated manual with a torque converter instead of a clutch.

As the transmission is a Nissan built unit do you think I could use Nissan Matic S which is fully synthetic?

[@leop3009]

I have a Nissan .... the type J is a JSW 3309 type fluid made by Exxon/Mobile or Impreial oil. Which is the toyota T-IV and Mobile 3309. (Mineral, non synthetic) Most probably your Kia uses the type J not the type S as its a 2007 ..... check the specs particular of the fluid . Nissan says tho Type S (synthetic) supercedes type J but if Type S is not available, Type J can be used (my Nissan Truck is a 2008 Pathfinder (6 speed, Aisin Warner) with type J as factory fill. Am using Toyota Type T-IV. No diff in shifts characteristics . It does have the half slip type of shifts .... if you know what i mean. Nissan didnt use the type S as factory fill till 2012 or 14 if i remember it . Same transmission model different fluid Your Transmission is a Jatco(Nissan) or an Aisin Warner(subsidiary of Toyota)?

So before I call the regular mechanic to check they replace the oil correctly, I want to try to find out if there is an acceptable substitute for SP4 that has another color.

[@DeusKDuo]

I don't see an issue for any use that says atleast meets the requirements. Some manufacture specifications will not get approved even if it can pass any real testing requirements even if it is superior to the manufacturer spec. For the life of me i can't remember which company it was but it will not license if a synthetic base stock is used even if it works wonderfully. I see it more as a way for these companies to decrease costs by not having to pay licensing and passing the cost savings to us. I can see Maxlife using a high quality add pack and base stock. Even hitech is saying it works in multiple applications. I would definately think with something like the oreilly one as it seems to barely meet specifications maybe should spend a little more and get something higher quality.

[@namenotshown9277]

australia here: if you dont have time to answer no probs. We have very popular brand of oils called Penrite, I use their atf fluids, price is not expensive. I note no licences on the lables but say "suitable for" etc. I use a clear plastic tube to fill the auto trans, I notice the clear plastic tube been sitting in the oil and its gone hard, lost its flexibility over a very short time in the atf fluid. There is common view atf fluids have additives to keep rubber in good condition, is this true? The seals are kept soft by something in the atf? I'm a little worried about this penrite brand atf since it made plastic tube go hard, I realise its not rubber but its got me a bit worried, I will try some rubber seal from old gearbox and test if it goes hard.

There are so many variables. We have a Subaru that uses HP fluid. I have been told many things that were not true and some that are. Subaru oil is made by idemitsu. This information is correct. Supposedly MATIC J is the same thing I dont know if it is. I was told that Valvoline multi vehicle Max Life fluid was a acceptable replacement. It was not and I wasted days and money and oil flushing idemitsu subaru fluid back into the 4EAT trans to get it back to running without slipping and overheating. use what you deem is correct but question every fluid before its added to you loved transmission. Sure quick oil places have a one size fits all (and ive been there and done that) but its not the best idea when after 15000 miles you trans has issues when just going OEM or OEM produced fluids will extend the service furthur. so be careful and listen here carefully.

I see your point about using factory fluid, but there must be some fluids that will work in these transmissions since Toyota and Volvo don't make the transmissions they are made by Aisin-Warner. What is a guy to use than for these transmissions? The Volvo fluid is even more expensive than Toyota fluid so a lot of people use the Toyota type-IV or Mobil 3309 in those transmissions.

I appreciate a lot of what this channel does but I think the argument is weak and using the term “counterfeit” is itself misleading. I need data that proves so-called counterfeit fluids are causing failures compared to “officially licensed” versions. The GM standard gives a recipe for meeting the standard. If someone orders Waffle House pancakes and I follow their recipe, did I make counterfeit pancakes because Waffle House didn’t license them?

[@MrRightNow]

It depends, would you still call those pancakes "Waffle House" pancakes? Did you use the exact same type of flour they use or just generic all-purpose flour from a nearby store? For all I know your pancakes might be more tasty or even healthier, but the only one way to know for sure that they're not worse than theirs is to have an official standard, not just few ingredients from the recipe, but maybe skip on other ingredients. And if you want to sell it as Waffle House pancakes, under their brand name, then you would also need the license from them in order to do that. Nobody stops you from using any transmission fluid in your car, but companies should be more transparent about what they sell and not abuse manufacturers trademarks, which can be deceiving to the consumer.

It’s not like transmission companies and car companies make their own oil. I’m guessing just like most people here are guessing, that oem fluids aren’t that good (meaning keeping them secret is purely for profit) and that big premium brands possibly make superior oils for the money.
