Rough Shifting of Automatic Transmission on Mercedes-Benz ML350

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.

I've only had my car from approximately for 2 weeks(used 2007). The first time I took the car for a test drive it was smooth riding. After signing the paper work and started home the car would not come out of 2nd gear. I turned around and went right back to the dealer. The sales person got in the car and hit a couple of buttons and the car was fine, except for a noise sounding as if it was coming from the power steering area. Brought the car back to the dealer the next day the owner acted like he didn't here anything; the car is in the shop at (dealer) Mercedes. It's been for three days already. I think this should have been consider a Mercedes RECALL!!!!!!!!!!!!!!! DOES ANYONE ELSE FEEL THE SAME!!!!!!!!!!!!!!!!!!!!!!!
The 7-speed automatic transmissions has problems with internal component failure that cause rough shifting going up from first to second gear and going down from third to second or second to first gear. Dealer says valve body replacement is needed. The cost: $2731.70. That's highway robbery!! Cant't afford it.
Hard shifts,after complete stop the suv will rev up and will not move then you have to shut off enginge restart and problem goes away I was told that valve body needs replacing and software upgrade Why this year ml350 has not been recalled
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 95,000!!!! stay tuned...
Rough shifting up/down to 1st and 2nd gear. Occurs at about 27 mph.
When going up a hill, it feels like I'm not going to make it because it's very slow until I take my foot off gas and then on again it'll pick up.
Slipping between 1st and 2nd and 2nd to 3rd when cold.
I bought my car approximately 16 months ago. I was driving at approximately 35 mph when i felt my engine begin ti idle. I pressed the gas and the car began to resume speed. I decided to pull over and check out the problem. I was satisfied that there was nothing wrong. Climbed back into my vehicle put it in drive and the car would not move. I tried reverse and the car would move budge. I have it in the shop now but I haven't been told the damages.
I had complained for over 30,000 miles of rough shifting, then was told it would be 1700 to fix, I went to an aftermarket repair and had it done for 1100, again, why hasn't it been recalled.
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.
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.
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.
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.
as listed coarse gear changes in low gears and sometimes leaps forward a bit from start off especially on steep uphills
Rough Shifting, Valve body repaired under warrenty.
I was told my Valve Body needed to be replaced, but now there are a host of other resolutions. I'm still a little confused on the entire problem but the bill was reduced considerably once I complained about this systematic problem with Mercedes.
Car seems to rough shift going down from 3rd to 2nd or going down from 4th to 3rd.
Suddenly at traffic light car won't move. The sound like a disengaged fly wheel emerged and the vehicle will not drive even when on gear. It was towed to repair shop.
