Audi A6 and A8 Transmission Problems

Audi has done a marvelous job putting together the tiptronic transmission  but it does have certain problems that make it a very costly repair. Audi does not recommend a transmission fluid change and it is a lifetime fluid but I would recommend changing it! After about 180k you can visibly see clutch wear material in the fluid. This clutch material will slowly start wearing on all moving parts at around 120k depending on driving habits, city/freeway driving. In many cases the actual clutch plate will wear to a point (typically 2nd gear and then first gear) that it sheers off its metal back plating. This will cause a loud clunk in the transmission and simultaneously the ECU for the transmission will flash the computer into limp mode.
