My trans. shifts very hard in auto mode especially in stop and go traffic and during hard accelleration. anyone else having problems?? It goes into the dealer tonite for for this problem as well as for the rear brakes, HVAC, and driver's one touch power window. Car has 5500 miles on it and I love it but these problems are completely unacceptable. If it needs a new trans I want a new car. (pissed)
