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.

When driving on the highway the car does not automatically shift into gear, it freezes. I have to pull over at the side of the road and turn off the car and restart it. I took it to a Mercedes dealership and they said they could not find anything wrong. This has occurred at least 6 times in the last year. Does someone have to have a serious accident to get their attention. The problem has never been fixed. Any suggestion how to handle the situation?
Transmission hesitates as if choking going from 1st to 2nd at slow speeds. Also just experienced loud clunking sound after shifting down and then back up from 1st to 2nd and later same thing from 2nd to 3rd.
the transmission gets stuck at a gear and won't shift up or down. I have to pull over and turn off and on the enginge to fix the problem.
Having same shifting problems as reported. I took in to my dealer and they upgraded software in both engine & transmission. Contined to have same problems and as this only happens intermittenly Mercedes dealer does not want to accept that there this is a problem. I should mention that this started right before my extended warranty expired. I threatended to post this ongoing problem with my car on Facebook and Twitter so others will think twice about purchasing a vehicle from the same dealership that I did and get the run arround from them.I recently received a phone call from the service manager and he put me in contact with the Mercedes manufacturer in New Jersey and am told they wwill work on getting this resolved. This was just within the last week so we will see what happens. I am not giving up and letting Mercedes off the hook for defective transmission parts that they should have recalled.
My 06 has on 3 occassions seemed to stay in 1st/2nd gear...it revs when I
hit the gas but doesn't go above 40mph no matter how much I depress the gas.
The only way I get it to stop and go back to normal is to shut it off and then
restart the car....this has happened about 3 times over the 2 years I've owned it.
My 2013 E350 transmission occasionally made a dull thumping sound when shifting from 3 to 4th gear (around 30-45 miles per hours). I took it into the dealership and could not duplicate the condition during my test drive with the service manager. He kept the car and ran a computer diagnostic on the car and found that it had a computer 'k" code error. They are replacing the transmission control unit (inside transmission). I hope this fixes the problem
Problem started prior to 100K extended warranty but dealer would not consider repair. I have continued to "baby"it and it still trucks on. It is the only real problem with a real great car. Usually I trade but well the economy.
Is ther a solution short of a new transmission? How much for that?
failed turbine speed sensor inside transmission causes car to get stuck in gear. Turning off engine and restarting temporarily fixes this problem. Part needs to be replaced. Plugging car into the Mercedes "Star Diagnostic" system will easily pinpoint this problem. Recommend going to dealer for this repair as they are well aware of it.
Shifting is rough when going from 3rd to 2nd and back to 3rd. Took it in and was told no problems and the software was updated. The problem
is still happening. It is frustrating because the people at Mercedes thinks I am being difficult. I have never had a car act this way.
Hard shift at slow speed.
I had a problem with the car not being able to get out of 2nd gear and wouldn't go past 40 mph at the most...I brought it to M_B dlrship and they replaced a part connected with the transmission and so far it's been working well....and that's about 4 months now.
Car gets stuck in gear - Won't shift up or down. Used to be able to turn off car and problem would dissapear for a while but now stuck in First. Dealership said transmission plate that holds solenoids needs to be replaced, at a cost of $1500.
Rough shifting from first to second gear when cold.
Dealer has looked at it twice with no solution.
This problem ussually happens during the morning while the car is still cold. There is a very hard shifting from first to second gear, where the car bucks. In addition, when shifting from fourth to fifth the gears seem to slip raving up the RPMs. I have taken it to the dealer, and according to them, they have not been able to duplicate the problem. I even had one of the mechanics take the car home with them so they can drive it in the morning. Still he says, he cannot duplicate the shifting problems. It has gotten to the point that I question my opinion on how cars should be shifting.
vehicle does not upshift beyond 2nd gear although RPM is extremely high.
It does the same thing that i read this is bad mercedez benz please make this a recall so we all can fixed this
Problem started in late 2009 when my car (22k mi) was under warranty but Mercedes dealership could not find anything wrong at that time. This problem has happened at least 4 times in the past two and half years. I used to be able to fix this problem by turning on and of the engine. Now (July 2012), the car (27k mi) stuck in second gear forever and check engine light is on. Dealership said the Conductor plate inside the transmission needs to be replaced, at a cost of $1600. Very disappointed with the Mercedes,
I have the same problem with my 2007 E350. It has roughly 56k miles and just stopped in traffic on 7/31/14. The car started back up and I managed to get out of the floor of traffic safely . The car is currently at the MB dealership awaiting repairs. This scared me to death. Thinking about getting rid if the car for a Honda or Toyato.
I had new 2015 E350 for only 2 weeks when automatic shifting problem started in lower gears. Technicians said it was computer glitch and had to be adjusted. Now it's doing the same thing shifting into D4 and deccelerating to lower gears too. Very annoying. I'll have to bring it back in to dealer to fix again.
rough shift 1 to 2 or down 3 to 2 up hills predoominately.
