I can't speak to MaxLife ATF specifically, nor to this application since it does seem to be a bit finicky. While it is prudent to use properly specified ATF, there is some exaggeration as to the differences in some of them that we see. Mola has already spoken to that. It's easy to claim that when I see something claiming Nissan Matic J or S compatibility on the shelf, it's not specifically licensed. That's true, but the actual ability to license a fluid is more the exception than the norm. Nissan can claim all they want that we should use OEM fluid or "equivalent" yet they don't seem to have anyone knocking their doors down to get an endorsement. They're also not going to convince me that their ATF is so proprietary and special that they make it themselves and somehow Shell, Castrol, and Mobil all have nothing to do with it and it's above their pay grade.

I will continue to use it in applications that I have had good results with (Ford Merc V, Toyota WS, GM Dex VI and Hyundai SP-IV).

While it does not cover all fluids, it works well in many, many applications.

MaxLife ATF works fine in my applications (and many others), is a better fluid, and cost less.



Great that it works for you but have you used it for 100,000 miles? Do you know if the OEM fluids have any proprietary ingredients these universal fluids lack and their absence might not show up for 100,000 miles? Transmissions are expensive to repair or replace so saving a few bucks on universal fluid isn't always the best idea.



Yes, I have. My 1997 GMC 1500 has 271,000 miles on original 4L60E transmission that has been lubed with Maxlife since 130,000 miles. It frequently tows up to 7,000LBS. A car transmission. In a truck. Towing. Maxlife is good stuff.

So is using Maxlife ATF in your transmission.


make the inside of your engine oil cap white.
don't use.

I read on this very forum that WS fluid can be replaced with ATF such as MaxLife (what I usually use), Redline D6, and Amsoil Signature.

I chose the MaxLife route and now the car has a shudder / slight bucking forward and back feeling after some gear shifts have completed and lasts about a second in duration....


Was there a complete fluid exchange or simply a drain and fill with a filter change?

His Cadillac has a Aisin TL-80SN which is closely related to the Aisin AA80E found in many upper end Lexus cars. Shares nothing with GM Powertrian 8Lx0E series units.

If GM could have skated by with Dexron VI in this unit.....I'm sure they would have....Dex VI isn't working so great in the GM 8Lx0E's either.

Clutch to Clutch transmissions can be VERY sensitive to ATF type! This trans calls for WS.

Though I would check the fluid level before doing anything!!

I don't see how? What compels oil companies to license/certify ATF's?

This sounds like an underfilled transmission to me.

I HATE WS, a horrid ATF if you don't have an external oil cooler IE Rav 4 (it shows it's group2/3isum). I myself only use Redline D6 and Amsoil SS in ATF. If I were to choose a problematic trans like yours I would pick Amsoil SS.

Amsoil and Redline are certainly great stuff, as is maxlife. It is surprising that maxlife is not performing well in the OP's trans. Or the fluid is low. Regardless, it would be worth discussing this particular application with Redline, Amsoil, and Valvoline reps before doing anything. Except checking fluid level, which should be at the top of the to-do list.

Great... now we're going to have bogus RJOD claims by people that can't read or use common sense. I agree, if you changed the fluid and immediately started having shift issues, you likely don't have the fill level correct. Also, did you pull the battery terminals to clear the shift logic or force clear the shift logic with a scanner? I don't know this Aisin so I will defer to somebody like clinebarger, but I know on my Ford and Subarus any time I did several D&Fs to replace a majority of the fluid, the trans did not feel right until I forced the TCM to clear itself and relearn the shift logic with the new, clean fluid. Ford had Amsoil ATL and all my Subarus (except the Forester with an MT) have and are using VML ATF without issue, so it's not confined to just MaxLife.

MaxLife clearly states it is a Dexron/Mercon type fluid, and if yours calls for a WS you should probably use something for that. But MaxLife is not a bad fluid for its intended uses.

Maxlife has the correct viscosity for WS fluid, so I'm going to side with clinebarger and others here- the most likely culprit is that your fluid level is wrong. Did you service this yourself or did you take it somewhere?

I just cant do it either, a transmission fluid that meets 30 specs...

Now if I had an old beater that needed Mercon or Dex III... maybe.
