'86 5K wagon auto tranny woes

[Alex Kowalski <akowalsk@shrike.depaul.edu>]

I just got a phone call from my dad today about his '86 5K wagon.  He 
just had the transmission fluid replaced by our local Audi man after a 
month of bad shifting and reports that the transmission needs 
replacement.  Apparently it is slowly grinding itself into filings. What 
cars/years does the Audi transmission recall/swap apply to and how can I 
find out if our Audi dealer will still change the transmission under the 
recall?

If this is impossible, can anyone recommend a good source for a used auto 
trans for this car?  

Thanks for any and all input,
