Auto gearbox oil change - a8 quattro d2

[Doug773]

Thank you so much!

Yes, mine is a faithfull 4 speed box, I've been keeping it for 10 years! No big issues so far, drive just right. But from some 4 years back, running idle it sounds like a diesel engine, no more that nice V8 muted purr. Asked some 4 different technicians to check it, they spent several hours checking every pulley etc and found nothing!
Maybe some valve clattering, I don't know. Otherwise the car run just great. It sounds OK at any rpm above idle.
Have you ever heard something like this before?

Many thanks! BTW, nice MJ pic, one of my fav artists!

Cheers,

Doug
