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.

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.

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.

as listed coarse gear changes in low gears and sometimes leaps forward a bit from start off especially on steep uphills

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.

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.

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.
Same problem as reported. My dealer and a Mercedes field rep have kept my car for weeks at a time while trying to resolve this issue. Your report that this is an internal parts failure, requiring disassembly may explain why they are not resolving this issue.
After reversing and switching to drive within the first 100 feet a grinding noise from the front driver side
a hard shift going uphill into 4th or 3rd gear
Read the recent law suit settlement with balance shaft issues, may 2015....it 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...
It does not shift the gear ,Does not move So i brought it the dealer(Loeber motor) they fixed the problem and i pay for it.
Same as described. Rough shift from 1st to 2nd gear. Downshift rough between 4th to 3rd and 3rd to 2nd gear.
