I have a '90 tsi that needs a tranny. I won't be doing it until the spring but I figured I would try and find one now. Let me know if you have one for sale. Thanks!
I've got a 91 tranny that's pretty decent. It would take a few extra 91 parts like the cables and shifter to work in your 90, but those parts are cheap and easy to find.
You should let me take a look into it, I may be able to help you out. Its also a good idea to have a spare too with these transmissions if your putting down good power.
I mean let me take a look at it as in you pull the trans, and I open it up and diagnose your problem. If I work on my trans I do actually rip it apart while mine is in my car, but thats my car
