2004 vw beetle convert. 1.8 turbo, 6 speed auto/triptronic trans. When car is cold shifts fine. about 10 minutes in to driving (not bad put noticeable) revse shifting 2 to 3 just a little. But on deaccel. shifts hard when going from 5 to 4. triptronic mode will work only from from park to triptronic, will work sometimes while driving. The PRNDS display on the dash will look like this going down the road [P][R][N][D][S] brackes around every gear selection and the numeric gear to the right will no longer display. auto mode or triptronic mode. Please Help I have no idea whats going on with this thing.
