[s-cars] Strange re-occuring clutch/tranny noise

[peter_schoettle at shaw.ca]

I have a 93 audi S4. I have had a strange reoccuring clutch/tranny noise. When I let the clutch out after downshifting , I notice a howling/whirling noise for a split second. It can sometimes occur on upshifting as well but it always occurs when the clutch pedal is being let out.

The problem may not show up for a month at a time. When it comes back it lasts about a half day or so and then is gone again. This has been happening on and off for the last 6 months.

My clutch feels fine.

Any insight would be appreciated.

Regards.
