Rough Shifting of Automatic Transmission on Mercedes-Benz E63 AMG

Problem Description and Possible Solution

Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. 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.

Car shifts hard from 1&2 more noticeable when cold and also downshift from 3 to 2 such that brakes are not needed. Going to ask dealer about a possibl
e recall
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.
Car shudders on acceleration in the first three gears. Feels like the transmission is slippling or converter isn't fully engaging.
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.
