My 1997 a6 c4 has a jerking problem on the first 2 or 3 times from 2nd to 3rd gear. This usually happens during my start up run even when the car is warm already. Atf has been changed twice already within the last 3 months. Used dexron 3 oil. Has anybody have the same problem (or better yet a solution)? overall, car is running fine. Would appreciate if any of you guys could help out.
