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?

    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.

    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.

    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.

    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 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.

    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?
