Got the car back. Service dept. acknowledges that there is a problem with the transmission but they do not believe it to be the solenoid problem mentioned in the TSB above, but rather gearset or clutchpack problem that is not "serious enough to receive a successful warranty claim". Whatever. It does seem to have cleared up a bit during straight line acceleration but I can still reproduce it in a slight turn, I rarely accelerate like this from a stop though, I like preserving my CV joints
So, the consensus was to just drive it (to me: beat the pi55 out of it) until the problem becomes more noticeable (to me: until I break it) or it throws a code. Time for some more 0-60 runs. I tried last night once and pulled a horrible 10.42 sec to 60. whatever is wrong with this tranny is definitely holding it back, it has to pull better than that yes?
