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.

    The transmission has been slipping since it was new, rolling back on hills like it was a manual. I have reported it since day one and they couldn't find anything wrong. It had a technical service bulletin on an electrical component outside the transmission performed in 2007 but nothing else. It now shutters, they say I need a new transmission and of course its long out of warranty. I've called mbusa and they don't want to hear about it because its out of warranty.

    Transmission oil drained out on own accord.

    Previously gear stuck and will not change down.
    Have owned over 35 cars in my life and never once had a similiar problem, should think that being a premium vehicle manufacturer, Mercedes would issue a RECALL on this concern.

    Will not most certainly purchase a Mercedes again, this is the 4th. one and the last one.
    No different from the mass manufactured garbage made in the USA.

    After long drives on the freeway, the car will accelerate slowly. It seems like there is a bit of hesitation between shifts. After driving a bit it will solve itself, but the problem is becoming less sporadic and more common. It is an automatic transmission.

    They just get a clog or choke in the gear shift up or down

    After I started my Mercedes GL450 and changed gear to drive, noticed roughness in driving. Pulled over and put the car in park and back into drive. This time it would not move. It seems it got stuck in nuetral mode with no indication what so ever on the dash board or anywhere.Had it towed to the dealer, they informed me that the automatic transmission pump is bad and they saw metal shaving in the transmission pan. The fix is to replace the transmission. They could not find the cause. They did aknowledge that there is an internal component failure. I called MercedesB USA, they informed me that they had no recall on transmission issues.
    How can I follow up on what you had stated that Mercedes released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

    My 2007 GL 450 is having shifting problems, It either is stuck in gear or will not move, causing to restart the car to clear the problem. I had to take the car in to get a new sensor plate 1300.00 repair bill.

  • I recently purchase used 2010 GL450. I notice the hesitataion in shifting mostly when after the vehicle has warmed up. It was sporadic, but I have noticed that it is lasting longer and longer and happening more often.
