Last year a friend of mine helped me install a shift kit in my 200. Everything seemed to be working fine.....then......i started getting extremely brutal 1-2 shifts. Felt like the trans was going to twist out of the car. 2-3 was almost as bad. And it was even pretty brutal into overdrive. So we adjusted the TV cable hoping it would help and it did on flat ground but when i would go up a steep hill it would skip shift back and forth between 1st and 2nd unless i got it up around 10 lbs of boost then it smoothed out and went into third. The trans actually felt smoother and less (a little too hard) at WOT. Any suggestions?
