no ,no i have changed Tranny oil...in fact twice since the first time i changed it at 65,000Kms (when the car had an accident and the radiator was smashed) and at 70,000kms when the new tranny oil cooler sprung a leak overnight. Therefore i have the oil thing covered. I dont think the tranny mechanically has a problem...as u can see the car hasn't really done much mileage. I am thinking it can be:

1, Tranny ECU problem
2, Throttle control
3, Vacuum leak

can anyone pinpoint this? The tranny chaNGES FINE ON THE HIGHWAY, tiptronic works well, but normal street driving, the car revs to a high RPM before gear changes...

 

YOu know mine just started doing the same thing, it all works fine for the most part except when you give it gas, and it reaches a shift point and revs high then shifts down with a big oll CLUNK, think this is electronic or mechanical?

 

Ran diagnostics at dealership. No codes, no errors...guess it's a mechanical problem. Even the dealership is stumped! I'm really confused.....need some advise. If the dealership cannot find the problem, who can?

 

Well my situation is the exact same! They can't find any codes or anything, the tiptronics(sp) could be the culprit Can anyone help us?
