Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

Very abrupt shift down if you hammer the throttle when already doing over 50 mph. Rough shift up from first to second and revs jump up in second gear as if a cluth was slipping.
Shift plate (PCM) failure causes the valve body assembly to make gear changes extremely rough in certain driving conditions. Not a cheap repair, The conductor plate (PCM) is a VIN specific part and has to be programmed to said vehicle at a dealership.
Hard shifting from 1st to 2nd and then down from 3rd to 2nd. Also hear a rattling under cabin just before the idle issue.
I have similar issue car shakes violently shifting into 3rd.
