Drive Train buck?
#12
the check engine light is not flashing, and i just had misfiring diagnosed and treated around 2 months ago. so i do know what that feels like.
would changing the oil in both the transmission/transaxle differential and the rear diff make a difference too? or could it just be residual kenetic energy being discharged through the drivetrain onto bad engine & tranny mounts?

I know this is an old thread, but it most accurately describes my issues.. Any fixes? I've got a 99 A6 avant with tiptronic. Under light load, under 2k rpm, I have a knock and hesitation I can feel in the cabin that feels like it might be related to tranny issue. Happens more when the car is warmed up. I can reproduce it pretty easily by accelerating to 50 mph, coasting, then getting lightly back on the gas in either auto or tip mode. Any help appreciated.

Thanks for the reply. I've noticed the problem primarily when the car is warmed up. I tried to reproduce the problem a few times while it was cold and couldn't. I wonder if changing the tranny fluid to a thicker one could help.. Atf4 ? Any thoughts? It wouldn't be cheap to do it right and not just flush it.
