A few years ago I had my automatic tranny serviced.  After I picked it
up the transmission was slipping.  When I checked the fluid level it was
over the full mark by maybe a cup or so based on the difference between
the two marks being .5 quart apart.  I took it back, they drained some
ATF fluid and it's been ok since.  Yesterday I had a (governor?) seal
replaced, and on the way home the tranny was slipping again (first to
second, mainly).  When I got home I checked the ATF fluid and, sure
enough, it was overfilled.  I took it back, they drained some fluid...
and it's been slipping every since.  The mechanic said there were some
filings in the bottom of the pan that were "probably from the clutch".

Both Bentley and the VW manual state NOT to overfill the tranny.

My question is, could those two instances of overfilling have caused
some damage even though the condition was quickly rectified both times?
Or, in removing and replacing the (governor?) could they have disrupted
some other critical adjustment that might be causing the slipping?

I need to deal with this Monday a.m. and would appreciate any feedback
from the list.
