2004 A6 3.0 Quattro-automatic transmission issues (somewhat long)

[Tony Hoffman]

The first thing I'd do is check the level, sounds like it may be low. You
will probably find his trans is leaking from the front drive axle output
seals. If so, pull and fix (and probably time for the outer boots as well).

The fluid mixing issues were in the 3-speed auto transmissions, long gone
from common new cars.

HTH,
Tony
