AUTOMATED CONTROL
Easier, safer, smarter hauling
With the m DRIVE 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
m Drive has got your back
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 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.

Power when you need it

Easy to operate
The m DRIVE transmission makes it simple and comfortable to drive a truck, opening up staffing to a larger pool of drivers. m DRIVE is automated, and that means less wear and tear on drivers. So they can finish the job strong and stay focused.
Minimal service
m DRIVE automated manual transmission is based on proven technology and superior design that requires minimal service and significantly reduces maintenance costs.
Reduced wear and tear
