I have a 92 300E, recently changed my trans fluid for my MBZ would not reversed. Noticed that the fluid was pitch black. Put regular dextron III trans fluid. after 3400 miles, it started to jerk and hesitate to reverse again. One neighbor who has a shop said to try to change my fluid to MBZ fluids, other neighbor with older model MBZ told me to have it adjusted. what do you think is best for me to do?[&:]

 

if your tranny fluid too dirty .the best is change the filter again ,
but sometimes you need to check the engine mount and tranny mount too.
