mDRIVE

The Mack mDRIVE transmission is an automated 12-speed, two-pedal automated manual transmission (AMT). This transmission maximises driver comfort, payload and fuel economy with an impressive base torque.

  • MaxBrake

    mDRIVE™ has got your back

    Pushing MaxBrake on the single DIN keypad optimises PowerLeash engine braking performance by downshifting if necessary, maintaining ideal engine speeds between 700rpm and 2100rpm when in braking mode.

    • Grade gripper

      Winning the uphill battle

      Grade Gripper eliminates rollback by keeping your position steady on an incline for up to three seconds after the brake pedal is released.

      • MackCellerator™

        Power when you need it

        Increase engine RPM while automatically downshifting the transmission and accelerating to enable a safe and quick passing maneuver. This keeps the driver’s hands on the wheel and eyes on the road.

        • Easy to operate

          The mDRIVE™ transmission makes it simple and comfortable to drive a Pinnacle™ truck, opening up staffing to a larger pool of drivers. mDRIVE™ is automated, and that means less wear and tear on drivers. So they can finish the job strong and stay focused.

        • Minimal service

          mDRIVE™ automated manual transmission is based on proven technology and superior design that requires minimal service and significantly reduces maintenance costs.

        • Reduced wear and tear

          mDRIVE™ features constant monitoring and intelligent shift strategies so there’s less stress on the driveline, resulting in a longer life for your transmission and more money toward your bottom line.
