A6 3.0Tdi Tiptronic, problem Help!

[cammy33]

I think I may have an issue with my gearbox? somtimes when changing from 3rd to 4th the revs can rise slightly approx 200-300rpm before the lock up happens. Is this a problem? The car has done 80k miles with Audi history. Thanks for any input.

Does it do it in "D" only?

Is it the same if you are in manual mode?

What revs are you at when it changes up and are you on W.O.T?

Is your car remapped?

[cammy33]

Normally about 3k RPM when I notice it, never checked in manual mode or paddles I will check tomorow. The car is not remapped, but I was tempted until I noticed this. Was out in car there and the 'box changes perfect appart from this glitch, even when pressed hard it changes smoothly. Thanx

If its an A5 it will be under 3 years old surely. Get it booked in under warranty for peace of mind if nothing else.

Title of the thread says A6! I am guessing but I have an inkling it won't be an A5!

Thanks, but its an A6. And its 2005.

Not does it say its an A6 it also says its done 80,000 miles so will be out of warranty. Why bother commenting if you dont even bother to read the question?

Worth seeing if your dealer (or a mate with vag com) can check the gearbox input and output shaft speeds - this could show the slipping if any.

Haven't heard of many failures of torque converters on this particular engine...

If it still doing it you could also see if there is an update for the transmission available from Audi - these are usually dealt with like a recall.
