Valvoline Maxlife ATF for GM GA6L45R?

Has anyone used Maxlife ATF in their GM transmissions? I am not due for one yet. But, I am in a year or so and I kind of want to start my research right now and be sure which fluid to use before I go ahead and change it or get it changed at my indy. I think Redline is the OEM for the GM Transmission fluid, right? What brand would you guys recommend?

The proper fluid (Dexron VI) is readily available and inexpensive so there is no point using a multi-vehicle ATF. As long as you use a licensed product, Dexron VI is Dexron VI. The spec is so strict there is little to no variation between licensed products.

You will receive two different answers. Those who have had great success with MaxLife, and those who will say "never stray from OEM fluid, the manufacturer knows best".


I run Maxlife in my GM 6L45 and it shifts great. I've personally had better luck with MaxLife than Dex VI in other GM transmissions especially the 4L60E in the Chevy trucks.

I ran that fluid in my 128i and it got rid of torque converter shudder right up and made the transmission noticeably smoother. Going to use it on my 328xi soon. It bothered me at first to use something that wasn't exactly and specifically made to be dexron vi but it seems to work very well.

Well and for most that experienced 1-2 and shudder issues, BMW did release a now-discontinued additive that actually resolved the issue in most cases. So to say the BMW stuff alone is gonna be good isn't accurate.

Im gonna change the fluid since this car had it when I bought it then it came back now after 20k miles. If it doesn't fix it I'll have to hunt for that additive.

This stuff is supposedly good for the shudder too.

You can't find the additive anymore. Discontinued. Believe me, I was willing to ship to Hawaii. You're gonna have to look for that back-room-forgotten-stash. I'm about to try that thing too, but I hear it's a temporary thing.

From what I've read, the BMW additive was basically the Lubeguard shudder fix but in a different package. MaxLife alone has helped fix the shudder for many.

I prefer to not use any additives if the fluid itself can do it so yes that's what I'm gonna try. When I got the car they changed the fluid at the place with whatever weird German fluid it supposedly takes but looks like it wasn't too effective long term lol

I think I'm gonna put maxlife in the e46 too. For how cheap a jug is, it's awesome how many cars it'll work for.

Well, if it was, it was in a more diluted form the size of a standard 1L bottle of oil. I used it a few times -- wish I kept some. But they all do about the same thing.

Well, I can get 2 gallons of Maxlife at Walmart for $35. Genuine BMW fluid is $70 for 7L. Is saving the extra $35 worth it? I haven't heard any bad things about max life. Just hesitant towards using it since it isn't BMW approved.

I haven't used the BMW fluid so I can't really comment on it. It might be better or it might be the same. If I could find it cheap enough I would try it on my own car but I have a jug of maxlife sitting around which would be a shame to throw away

The previous owner had the transmission fluid changed @BMW when the car had 61k miles. I do notice the transmission has a hard shift going from 2 to 3 but it only happens when the car is cold. I started to start the car early and leave it started for 5 min before I drive it and it doesn't "Jerk". I've heard its a normal thing for the E9x chassis.

just changed the original fluid on a 146k trans to Maxlife and noticed improved shifting, I'm really happy so far! The original fluid was pretty bad needless to say!
