  1. Automatic transmission (power train)

    NHTSA 84V007000 Reported 54,056 vehicles potentially affected MERCEDES-BENZ USA, INC.

    The automatic transmission downshift linkage adjacent to the engine throttle control contains a plastic bushing that could deform due to high engine compartment temperatures created by the catalytic converter.

    Remedy: Plastic bushings will be replaced with steel bushings.

    Model years: 1977, 1978, 1980

  2. Automatic transmission (power train)

    NHTSA 80V160000 Reported 16,312 vehicles potentially affected MERCEDES-BENZ USA, INC.

    The plastic bell crank bushing for the pressure control rod of the automatic transmission could deform due to high temperatures in the engine compartment produced by the catalytic converter. This can cause the control rod to dislodge. A dislodged rod may prevent the nearby engine throttle linkage from returning to the idle position.

    Remedy: The dealer will replace the plastic bushing with a metal one at no charge.

    Model years: 1976

  3. Emission control (engine and engine cooling)

    NHTSA 78V106000 Reported 10,500 vehicles potentially affected MERCEDES-BENZ USA, INC.
