Eaton Cummins Automated Transmission Technologies is expanding its Endurant automated transmission lineup with the introduction of the all-new Endurant XD series. These are purpose-built, high-performance automated transmissions designed for on-highway applications with high gross combined weight ratings, such as double and triple trailer trucks, and severe-duty on/off highway applications like dump and logging trucks.

The Endurant XD series has torque and horsepower capacity to cover all Class 8 North American engines, the company said, including the Cummins X15.

“The DNA of the Endurant platform is efficiency, light weight and low cost of ownership,” said Charles Masters, general manager, Eaton Cummins Automated Transmission Technologies. “We’ve taken that DNA and added the durability and unique features that customers demand from trucks operating in severe heavy haul and vocational applications to create the Endurant XD series.”

The Endurant XD series is currently going through an extensive development testing program that puts the transmission through evaluations under extreme conditions.

The Endurant XD series has 18 forward speeds, making it highly versatile and allowing it to be used in many applications and driving scenarios. It is designed for ease of use, with low-speed maneuverability, up to six reverse gears, and optimized software that makes smart shift decisions in difficult conditions. The Endurant XD series features provisions for bottom 8-bolt and rear 4-bolt high-capacity power take-offs, and a transmission oil cooler provision is available when required.

Endurant XD transmissions will be available starting in 2021.
