mDRIVE™

The Mack mDRIVE™ transmission is an automated manual transmission built for Mack Pinnacle™ tractors. This 12-speed, two-pedal transmission not only delivers smooth shifts every time, but also maximizes driver comfort, payload and fuel economy.

  • Automated manual transmission
  • 12-speed, two-pedal
  • Direct drive and overdrive offerings
  • 1,920 lb.-ft. torque capacity

  • Automated control

    Easier, safer, smarter hauling

    With the mDRIVE™ automated manual transmission, there’s no clutch pedal, and shifting is operated by intelligent software and engine integration. It continuously monitors changes in grade, vehicle speed, acceleration, torque demand, combined vehicle weight and air resistance to optimize fuel economy on every drive.

    • Auto neutral

      mDRIVE™ has got your back

      mDRIVE™ shifts to neutral if the engine is turned off to prevent accidentally starting the truck while in gear. When the parking brake is applied and the transmission is left in gear, it will automatically shift to neutral after four minutes to reduce the load on the drive train.

      • Grade gripper

        Winning the uphill battle

        Grade Gripper keeps your position steady on an incline for up to three seconds after the brake pedal is released. So there’s no dangerous or awkward rolling backwards when stopping on a grade.

        • 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.
