Verified

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.

    felt a "clunk" at first/second upshift at low speeds, worse when hot.
    Dealer found "large pieces of metal" in transmission and torque
    converter. Dealer replaced both.
