I purchased a used 2012 Focus SE with the 6 sp powershift. It has over 20,000 miles and and behaves like everyone has posted here (shutters/jumps at slow speeds, shifts upward too early, rattles,etc). So I'm pretty sure it has not had the transmission flash/reprogramming. I saw the TSB on the 1st page of this thread. Is there any updated TSBs? I don't have time to look through all 172 pgs here. I plan to schedule an appointment at the dealer soon.
Thanks for the help.
