Built for precision shifting.
Mack’s industry-leading automated manual transmission expands your driver base, reduces costs and delivers the smoothest shifting around.
Shift your thinking
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.
Automated Control
m DRIVE 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 drivetrain.
Auto Neutral
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.
Grade Gripper
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.
