Car is all good after many more miles testing the trans out. Must've been acting up from only a half quart low out of 12. Interesting.

It seems to be fine now, but I'll report back at some time in next several days to confirm. He said most vehicles won't be picky over half a quart and he wouldn't give it a second look if that was the case on a vehicle, but that if the fluid being less than a quart low was causing the issue...

Shop is looking at it now. Topped off fluid with what was said to be less than a quart and it's being test driven now.

We'll, I spoke too soon. The transmission slipped out of gear for a good ten seconds today on my way into town and transmission went into limp mode. Now I don't know if it was the fluid or the flush that did it, or if it was low. She only has 43k miles on her. I'll keep everyone updated. The...

Car is behaving normally again with the WS-type fluid from ACDelco. I guess MaxLife isn't the best option for a WS-type application for anyone wondering. The transmission operated and didn't fail or anything, but it didn't operate as smoothly as it could and it didn't give me confidence in the...

Originally Posted by alchargo As slacktide and E150gt have already pointed out, I doubt the problem is with the fluid and instead an issue with the transmission itself. There are numerous complaints about the 8L80E and 8L90E describing your exact symptoms. There's even a class action lawsuit...
