There is nothing wrong with the 5Tip. The failure items are a specific item that is common to all ZF transmissions of the era which has zero to do with power output of engine. I have rebuilt two 5Tips here in the past couple of years and the failure is from the exact same thing - pressure regulator which blows out the A-drum clutch. Once this is corrected with the updated design you're good for years upon years. People have been mislead for years on this item which has created a misguided lack of understanding and panic to these cars. Bottom-line Audi (and BMW/Jaguar/Merc) should have issued a service bulletin to all owners that indicates the lower valve body should be replaced/overhauled at 80-100K due to the natural wear inherent in the design and you wouldn't "blow the tranny"....
