w126 transmission behaviour???
 

My 380's transmission is acting up! When you shift from P to R there is a delay and then the car slams into gear abrubtly. The same goes for P to D or R to D.

A mechanic of Mercedes told me that I need to a adjust a pressure modulator and that is the problem. It was checked for vacumm leaks and there wasnt any.

My dad said he did change the pressure modulator for the tranny a few years ago and it didnt make any difference. He got it from a used w126.

Any ideas????
