The transmission in question is not the GM 8 speed.
And yes, it is the 8 speed transmission, but made by Aisin. Maybe the other poster meant the Aisin and said GM since it's used in some GM vehicles. I've made the same mistake before.
It is an 8 speed, but not the GM 8 speed, which is the 8L90.
Was the fluid level checked prior to dumping the MaxLife?
The fluid level was checked by the tech (who is always assigned to me whenever I come in as I'm picky with my cars) prior to the change and it was fine apparently. I don't know if someone else would notice the transmission issues in a car with less horsepower since it wouldn't be straining it as much on shifts and may not be noticeable, but in this transmission paired with this engine, every little nuance is apparent (at least to me).
