Endurant HD automated transmission

Intelligently engineered

Endurant HD was designed, engineered, and created from a clean sheet to be an automated transmission…not simply an update to an AMT. This allowed us to optimize the transmission’s weight, dimensions, and features. It’s the lightest heavy-duty automated transmission, yet capable of handling 1,850 lbs.-ft. (2508 Nm) of torque. Drivers will appreciate the smooth and intuitive shift strategies and low-speed maneuverability. Integrated communication between the engine and transmission allows predictive shifting and GearLogic™ features to improve efficiency and performance.

Protects your investment

With Endurant HD, you know it’s going to last. But to make it last longer, we’ve developed several smart features like a transmission fluid pressure sensor. It notifies you of a developing problem and safeguards your truck—before it’s too late. Our 430mm, self-adjust clutch is maintenance-free, which means it requires no adjustments or grease. 

Easy to maintain

Getting the most out of your transmission between maintenance intervals means  Endurant HD needs to last longer. So, how about an oil life of 750,000 miles (1.207.008 km)? That’s 250,000 miles (402.336 km) more than the competition. All while using half as much lubricant as competitive automated transmissions.

More ways to get the job done

Endurant was designed from a clean sheet using decades of transmission expertise and tested in the most extreme environments to ensure reliability. Even its name speaks to its ability to handle the rigors of day-in and day-out, heavy-duty trucking. Because there’s no one transmission that’s right for every job, Endurant offers choices - direct drive and overdrive models, and single and dual PTO mounts - so you can choose what’s right for your fleet.

The 12-speed overdrive and 11-speed direct drive models are lightweight, yet rugged, and loaded with features that minimize maintenance.

The new dual PTO option provides customers with two PTO mounting locations: an 8-bolt bottom mount and a 4-bolt rear mount with a combined 95 horsepower capability. A single PTO model with an 8-bolt bottom mount location is also available, giving fleets enhanced flexibility in the secondary market.

The introduction of Endurant and the PACCAR transmission were so significant that the editors of Heavy Duty Trucking recognized them as one of the top 20 products of 2018.
