motor mount or shift linkage mabey.., or its just being a normal vw with its minor flaws Oh yea, make sure your tranny fluid is topped off and/or changed you know. number one cause of transmission failure is heat. good luck!

Do you have the Linkage System? Cause if you do then it might be those links, cause mine did the same thing.  

maybe the clutch or the rev gear is not going in fully, so its, kinda touching, but it skips, like maybe the linkage is to lose for rev.
