So I'm considering parting ways with my 2002 aero MT and getting a 2002 aero AT. Main reasons for this thought are the color, AT is black and has 110k miles less than my 5 spd. But that may mean abandoning my hopes of going with a 19t turbo and forged pistons. If the car is not raced or beat often will the automatic trans hold with a stage 3~4 tune? I've been reading mixed opinions on it.
