86 4kq buzzing sound at around 4000 rpm

Greetings all,

Well the clock says 157k and it looks like i'm about to embark on my next Audi
repair adventure.  Here's the symptoms:  On acceleration between 3500 and 4000
rpm there is a buzzing sound coming from the front of the car.  It also happens
at a steady 4000 rpm  It seems to be transmission related because it goes away
when the clutch is depressed.  Any Thoughts.  Think I'll get stranded someplace
in the north country of New England?

Thanks all,

John
