Geared up for any job.
Available with optional 13- and 14-speed creeper gears, the Mack m DRIVE™ HD transmission provides flexible gearing for low-speed applications, as well as improved startability for heavy loads, while maintaining proper gearing for fuel efficiency at speed.
Roll over your toughest challenges
mDRIVE HD is engineered with two additional low gear ratios for vocational work, plus multi-speed reverse gears for more startability, maneuverability and flexibility in low-speed applications. So, no matter the job, you’ve got the ability to dominate.
Low-speed creeper gears
When rocking won’t release your truck from sand and loose soil, mDRIVE HD allows you to raise the engine RPM and torque before engaging drive mode to free your vehicle from spots that would sink the other guys.
Power Launch
Grade Gripper holds the truck 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
Don’t let troublesome terrain bog you down. When your truck gets stuck, mDRIVE HD rocks the vehicle back and forth to break you free.
Rock Free
Maximize Mack PowerLeash engine braking, with downshifts to high RPM to provide the highest amount of compression braking available.
MaxxBrake
Seamless integration
Mack's m DRIVE HD continues over a century of setting the gold standard for powertrain integration. This transmission was designed from the start to work in tandem with your Mack engine and axles for improved fuel efficiency, increased uptime and lower total cost of ownership.
Increased driver productivity
The automated m DRIVE HD means less physical stress on drivers, so they can finish the job strong and stay focused. Moving from 0 to 60 takes only three moves – compare that to the 60 moves needed with a manual transmission.
Lighter than the rest
Even though it’s built strong,
m DRIVE HD is hundreds of pounds lighter than the competitors, so you can ditch dead weight and increase your payload.
