The automatic transmission in the 2003 Jetta TDI in my sig line has finally gone to tranny heaven. I'm looking for a source for a (hopefully inexpensive) replacement transmission. Several VW mechanics have told me that it's possible to replace an automatic with a 5-speed manual in these cars, so I'd be interested in either. Given the age and mileage of this vehicle I'm not looking to spend a lot, but I'm leery of just getting a cheap used "as-is", especially since the automatics in this model are notoriously unreliable to begin with. Can anyone point me to a recommended source for used/re-manufactured VW transmissions? Thanks.
