The transmission slips violently between 2 nd and 3 rd gear. there was a complete loss of power with the pedal down completely. after research have discovered that the design of these triptonic transmissions which can be switched from manual to automatic are faulty and costly to repair. i am considering a valve body replacement which may or may not fix the problem. audi does not stand behind their product. this is a common problem among audi owners. *tr
