Mack’s mDRIVE™ XHD Transmission-Geared Up for Any Job

Available with 12, 13 or 14 speeds, as well as multi-speed reverse.

Mack’s mDRIVE™ extreme heavy-duty automated manual transmission is available with an extended range of gears—including additional low ratios plus multi-speed reverse gears—allowing you to slow it down for jobs that require extra precision or speed it up to take on your roughest work. It’s built light to make Mack® Granite®, Anthem™ and TerraPro® models even more productive. Because when you’re faced with the most challenging jobs, mDRIVE XHD’s flexibility helps you keep driving to the top.

The mDRIVE™ Extreme Heavy Duty automated manual transmission is standard on the Mack® Granite®, and is available for the Mack Anthem™ and TerraPro® models, so you can rollover your toughest challenges. This transmission is offered as a 12, 13, or 14 speed, with optional low gear ratios and provides up to 2,060 lb.- ft. of torque, horsepower ratings from 315 to
605 HP, and is designed to integrate seamlessly with Mack MP® engines.

Mack’s mDRIVE XHD is engineered with two additional low gear ratios for demanding work, plus multi-speed reverse gears for increased startability, maneuverability and flexibility in low-speed applications. So no matter what jobs you face, you’ve got the ability to dominate them.
Don’t let troublesome terrain bog you down. When your truck gets stuck, mDRIVE XHD rocks the vehicle back and forth to break you free.
(Optional with Mack Fleet shifter package)
When rocking won’t release your truck from sand and loose soil, mDRIVE XHD allows you to raise the engine RPM and torque prior to engaging drive mode to free your vehicle.
(Optional with Mack Fleet shifter package)
The mDRIVE XHD is available with up to six different combinations of rear transmission-mounted PTO options and a selection of factory-installed piston and gear-driven hydraulic pump options

Get maximum performance from your engine brake. The engine, engine brake, and transmission work together for a controlled descent speed without overspeeding the engine.
There’s no awkward and dangerous roll-back when stopping on a grade. Grade Gripper keeps your position for up to three seconds after the brake pedal is released.
(Optional with Mack Fleet shifter package)
Enhanced Construction Shift maximizes gradeability and improves starting and shifting on rough terrain.
(Optional with Mack Fleet shifter package)
Designed for the trucks that shoulder your largest loads, Heavy Haul Shift offers even more performance-oriented shift points and less skip shifting. Recommended for loads over 160,000 GCW.
(Requires Mack Premium shifter package)

As part of Mack’s legendary integrated powertrain, mDRIVE XHD works seamlessly with Mack engines and axles for improved efficiency, increased uptime and lower cost.
The mDRIVE XHD is serviced by Mack’s industry-leading dealer network. Forget the additional time or hassle of third-party repairs.
Because mDRIVE XHD is automated, drivers don’t have to worry about shifting gears—they’re more rested and ready to finish the job with increased focus. And now that it’s offered with additional low ratios, drivers can more easily adapt to whatever the job demands, allowing for increased productivity and performance.
Even though mDRIVE XHD is built strong, it’s hundreds of pounds less than competitors, so you can ditch the dead weight and increase your payload.
