Not B+G ofcourse, but all these other brands such as Royal purple, pennzoil,GM, and a few others. From a crash course I recieved from Eslia and a bit of personal experience, you should only use something with a viscosity of 75w90 and a GL-4 rating or better. I know there is a lot of misguided info on tranny fluid and someone should make a sticky about it, boy it sure would have saved me alot of heart ache. Anyway I'm going to put the right stuff in and see if it helps. If not I'm going to try and work one over on the dealer.
