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.

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.
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.
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.
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?
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.
Transmission will not shift put iof 1st gear...the rpm is up to 40-50 and the car wont go faster than 32 without pulling rough.
The car sometimes won't shift higher than 2nd gear or 3rd gear. I have to pull over and shit the car off. Then re start it and it is normal?? It does this once in a while. No light on, no codes, the dealer says to replace the ETC? Electronic transmission control?? Maybe I'm not saying the right part? But it's a $3900 fix according to a Benz dealer. I will keep driving it until it becomes frequent or breaks down completely
Came to a stop at a stop light in my 2006 350 CLK and when I tried to accelerate the car would not move an inch. Put the car in park and shut it off and started it up again and still nothing. Tried a couple additional times and still nothing. Have never had this happen ever before and have owned dozens of vehicles. Have babied this car and has been dealer serviced since I have owned at 50,000 mi. Have spent more fixing this car than any vehicle I have ever owned and have had multiple Porsches, 500SL Mercedes and domestic cars and trucks.
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.
no solution at this time.
Just started, it occasionally will slow shift, and miss upshifts by staying in lower gear up to 5000 RPM. Manual shifting (L-R on stick) seems to force it, but am afraid it's going to become worse and leave me stranded.....
My 2006 is stuck in 2nd gear and check engine light is on. Can't drive.don't know what to do
Rough shifting from 1st to second. (Automatic)
check engine light on, car stay on low gear only
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
