Ustaad Asghar, a veteran VW only mechanic may not be as big a name as Ustaad Khalid/Westeridge RWP but he surely knows his work. Succeeded by his eldest son, Zeeshan Asghar (aka Shani), the duo has been working on my cars since 2000 ever since I have been in the hobby. Never failed me ever for all these years.
I would recommend them for all things VW but transmission, as I have no experience with the duo on the subject. Their address/contact information is in the Subject of the Recommendation.
