Mercedes-Benz C350 Problems

Rough Shifting of Automatic Transmission on Mercedes-Benz C350

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.

big bump feels like going over a speed bump at 30 mph not sure if from the trans or rear end it lunged me forward when it happened
Shifts badly almost a jerky feel 2 to 3rd gear automatic transmission regular schedule maintenance done
When first starting out driving car shift jerk after 15MPH then jerks again when I start to slow down around the 15mph speed. I have a automatic so I guess it jerks coming out of 1st gear going to 2nd and downshifting out of 2nd to 1st before car comes to a complete stop
Rough shifting of the automatic transmission from 3rd down to second and second down to first.

Also from 1st up to 2nd and 2nd up to 3rd.
Car seemed to shift a little hard from 1st to 2nd gear when purchased with around 60,000 miles but recently got bad around 102,000. Shifting up & down around 1,500-2,000 RPM is very jerky, as if driving a manual in 2nd gear all the time. It shifts hard unexpectedly when letting off the accelerator. It sometimes lurches forward while at a stop with foot on brake (very scary). A few times recently when accelerating from a stop it felt like it was in neutral and didn't want to go, then suddenly started going as if shifted into drive or something suddenly "caught."
