differences between a 97' 4l60e and 98+
thanks.
Here's the situation, my friend is putting an LS1 into his 97 formula A4. It's a GM crate engine so he doesn't have a matching tranny. He was thinking of using his A4, I knew the TCs were diff, but wasn't sure what else.
So my next question is, can he use his tranny and if so, what changes need to be made.
Thanks!
