I have a question out there for all you people with a Step-Tronic. When I'm driving around normally and I'm in 5th gear everythings all good. When I come to a stop or slow down a lot, the tranny shifts down to 2nd gear by itself right? That part is normal... This is also in the S-Mode. My problem is when the car shifts down to 2nd, I feel my whole car shake or shift. The sound I hear is kinda hard to describe, but the closest sound I can describe it as is a "thud." My cars only 4 months old, and I've had this problem for as long as I can remember. Anyone else have this problem? If it is a problem... Thanks.
