Doug,

My engine did literally rock from side to side shaking the whole car. If you saw vibrations other than that, it may be an indication of other problems..idle set too low, or rack damper screw too tight (if w116 diesel has one), dirty or worn injectors.


The vacuum control valve I am speaking of is white plastic and it sits on top of the injection pump. This may be out of adjustment or a vacuum leak somewhere (including the vacuum assembly that site on top of the valve cover). As the techs on this site have said before...adjusting the transmission should be done by someone who really knows these MB trannys.
