I finally got the recall/technical program letter in the mail, and have scheduled to have it done. Just wondering if anyone else had something similar and if the update helped. FWIW I still love the trans, and am hoping the update improves the "S" mode as some on here have experienced.
this is my experience except i have a nov 11 build with 16000 miles and have only recently started experiencing bucking it seems if i don't accelerate the car just cant shift properly
oh and i was posting that tsb because it seemed there was a argument over whether or not the car did that
