Transmission specialist in Delaware Valley/Philadelphia area?
 

The dreaded hunting, delays and rough shifting have become almost intolerable in my 1998 A8 at 75k miles. Can anyone recommend a good, preferably inexpensive but good transmission shop that can fix the A8 trans problem? Somewhere around Trenton would be ideal, but anywhere in the greater Philadelphia area is fine.

Have you done a transmission service?
 

I would certainly try that, first.
