Eric - I'm fighting a trans. problem.  The tranny and diff are two 
separate systems and require different lubes.  The diff does require 
a synthetic, as use of standard lube eventually results in failure 
unless the owner is fanatic about keeping the level checked.

I think it is CRITICAL to change fluid often in the 5K -100-200 
series.  I am investigating this - and have found that there is a 
specific and VERY expensive failure of pump and 1st/rear shell.  One 
dealer in Austin has done *30* rebuilds or trans. replacements, most 
on 100/200 models.  My opinion is that this transmission is NOT 
enough for the car - especially turbos - and is excessively failure-
prone.  I'd love to go after Audi as a group, but don't know that I 
will go to the trouble.

I have also been informed that it's cheaper to replace the whole 
trans. than to rebuild - the mechanic gets 30 hours labor, plus parts.

So - what am I going to do when the DAMN thing is back together?
1)  Run synthetic trans. oil
2)  Change at no more than 30K intervals

The trans/diff seal, according to what I've heard, is a bogus issue.  
There is no direct connection and flud interchange should not be 
possible.
