Noise from T85 quattro Gearbox

[Doug Johnson]

The local VW dealer in Wichita told me the speed-related noise I reported to
them is coming from the "transmission," and it needs to be replaced.

Any thoughts on what, in particular, inside the box might make a
speed-related noise?  It's not a whine or a grinding sound, like I'd expect
from a an impending bearing failure.  It actually sounds like wind, or some
very light rubbing.

I appreciate any thoughts.

Thank you,
