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.

While driving my car I guess the gears shifted because the RPM was going into the 4 and 5 range while trying to make a turn onto the highway. Then realizing that I did not move the gear by mistake, my car would not go above 25 mph. When I finally got home it was a burnt rubber kind of smell coming from under the hood. The past few times I visited my local dealership and complained about the transmission jerking they said it was nothing. Now my car is in the shop waiting to be seen...

My transmission needs to be replaced. Something to do with a pump?
Hi! My gear box stuck on a high gear like "3" or "4". I must turn off the engine and then turn it on to fix this problem.

Feels like a gear change problem when slowing down. Car slightly jerks forward periodically at starts or stops. Starting up, putting foot on brake and shifting into reverse sometimes there is a rare thumping noise. Also, car slides/jerks forward when reversing from a down slope park mode. That was a little alarming. Thought car was going to slide down embankment. The car also slowed down after a block from starting location. Engine sounded strained. I pulled over because I thought I too had hit the gear shift accidentally which was not the problem. I waited parked a few moments and started driving again slowly. There was not another problem. Obviously from the other similar complaints, there is some factory problem going on here.

My CLK-350 "check engine" light is now on, transmission is stuck in second gear and will not shift. I recently had the conductor plate changed in the transmission...still no good. I have no idea what kind of expense I am looking at. I have heard it will cost me approximately $8,000 to replace the transmission. I am sick over this.

i was coming from a red light onto an access road trying to build up speed for the highway, noticed that my RPM's were reving to 6000 but my speed was only 20 or so. had to pull off to the side, put the car in park and turn it off. once i did that, i had no problem with it going. this is the second time this has happened.
It just started. It hasn't been fixed yet. We are really disappointed. The brakes had to be replaced. The alternator went out. We had to have some other electronic malfunctions repaired not too long after we got it. Now this. It sounds like it will be an expensive repair. We took it to the dealer and they couldn't figure it out. It had a 1405 code and some communication faults with the transmission which started in ESP and instrument cluster.

Transmission won't shift to higher gear and sometimes won't shift to lower gear. If I shut the car off and then restart engine it works fine. On going problem.

When in D DRIVE, the car will proceed slowly, have to shift to 2, 3, 4, to proceed at normal pace. This problem happens intermittently, but when it happens, this could be dangerous if on a hill.
2006 CLK 500. Gears will not go past 3rd gear and is stuck there even if I try to manually shift up using the tiptronic pads. FML
