Rough Shifting of Automatic Transmission on Mercedes-Benz ML350

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.

Read the recent law suit settlement with balance shaft issues, may covers transmissions up to 2007 and mine is having the same problems shifting (shuddering on acceleration). My dealer supposedly never heard of it...I am in the process of educating THEM with the settlement....we will see if they fix it! I've put over 256,000 miles on my 2001 ML320 with no problems, and this 2009 ML350 is dying at
stay tuned...
System started slipping not as I was driving seems to stay in the first or maybe the 2nd gear and will not shift manually when trying to put it in 1 2 3 or 4 gear.. How much does it cost for this to be repaired.
It just happened as I was getting on an on ramp to the freeway. The transmission wouldn't shift into passing gear. It stalled and after a few hundred feet, and reduced speeds, it finally re-engaged. I smelled a burnt smell as well. I haven't had it repaired as I don't know what the cost will be. Has anyone else experienced this issue? Is there a recall on this part? Mine is a 2004 ML350.
I purchased a new '15 Mercedes ML 400 and noticed the sudden jerky movements as if I was driving a stick shift. Shifting from 1st to 2nd to 3rd is not smooth at all especially letting off the gas from 4th then down shifting automatically is when I can feel a sudden jerk.
My gear selector won't change from first to second gear,it is stuck and won't display on the panel whether on drive or on manual gear
My 2006ML 500 had this problem almost from day one. Dealer kept telling me it was normal. Rough shifting first to second and quite a bit in down shifting.
Unhappy for 10 years. Finally would not shift at all. This past week took it in because it would not shift out of 1st gear. About $1300 for parts and $900 for labor, the shifting is as smooth as it could be. A CTRR. Unit electrohyd. Was needed, some kind of valve body needed. Until now never liked driving this car. In my opinion this all should have been done during warrantee. Bought this car new. I took out 7 year , 100,000 mile policy. Never had a problem with any other car I bought.
Just purchased vehicle 6 wks ago. Researched on Consumer Reports and CarFax prior to purchasing. Been having difficulty on certain long, steep hilly roads. Cant get vehicle to shift over 40 mph. Removing foot fron accelerator to reshift does not help. Having difficulty stepping on accelerator to pass slow vehicles on highway. Vehicle just does not move out of its own way. Looked problem i was experiencing up online today and discovered all these complaints. Since it is a widespread problem, not limited to a specific year or individual vehicle, mercedes should be held accountable and recall these vehicles. I was under the imoression i was purchasing reliability in purchasing mercedes.
Problems at low speeds and while attepting to stop. Rough shifting. Metal shavings were found while checking the fluid. Parts had to be ordered and front trans was taken apart and fixed. A month later I'm having shifting problems again.
Shifting from 3rd to 4th. But once in 4th no problems until it has to down shift to 3rd and then you have the same problem no matter if transmission is hot or cold.
1-2 shift when first starting out{ live on an uphill grade} acts like the transmission goes into neutral before completing the shift .
Now I have a check engine light on.
Occasionally slams into gear when shifting down to 2nd or 1st gear, especially when reducing speed quickly. Each time it has been taken to the dealership (3x for this problem alone), I am told they adjusted the computer. Since it is an intermittent problem, difficult for then to diagnose but has gotten progressively worse.
