Car Repair

I am a service tech, very conversant with car repairs, but would need some skilled training on how to repair and rebuild auto transmission system on vw and audi cars, incl the zf, multitronics etc.is there any available skill centre for such training? any helpful input would be highly appreciated! thanks.

Vw and audi have technical schools on their own but they only train people who will be working for them. call them up, they might know some outside schools.
