I just bought an 2004 SMG M3 (a week ago) and the car slips out of 4th a little into another gear. It has over 100k miles on it. I have been reading about SMG on the board and has scared the crap out of me. Should I start saving my pennies for a new tranny?? I see all the negative posts on the board about problems but how many people have high miles and no problems with their SMG?
