Hard Shift 1996 W210
 

I just had my belt tensioner shock replaced and there are several vacuum lines running in front of it. Right after having the work done my car is shifting as though a mule is kicking the car- not good! Anyone have an idea as to which vacuum line might be the culprit? Also, could the two lines next to each other be switched? Is it the vacuum check (blue) that's dead?

Any help is appreciated.

thanks in advance. I'm going to muck around with it but thought someone may have insight and save a guy some time.

thanks
