Truck manufacturers Peterbilt and Kenworth have announced the availability of the new 12-speed Eaton Endurant transmission in some of their most popular vehicles.
Introduced by Eaton Cummins Automated Transmission Technologies, the Endurant transmission is engineered for seamless integration with the Cummins X15 engine to provide excellent fuel efficiency, performance and low-speed maneuverability. The transmission offers engine ratings up to 510-hp and 1,850 lb.-feet of torque and will service vehicles in regional and linehaul applications up to 110,000 lbs. GVW, while providing weight savings of up to 105 pounds less than competitive automated transmissions.
It is now available in Peterbilt models 579 and 567 and the Kenworth T680.
“The Endurant transmission was optimized for the Cummins X15 engine and gives our customers another powertrain option,” said Scott Newhouse, chief engineer for Peterbilt. “Endurant has a wide range of benefits, including its lightweight design and longer service intervals. Its integration with the column-mounted shifter will make it a top choice for both fleet and owner operator customers.”
The Endurant transmission comes standard with the PACCAR column mounted shifter, putting gear selection and engine brake controls at the driver’s fingertips for better ergonomics and improved performance.
A cooler-free precision lubrication system, encapsulated sensors and wiring, and standard 8-bolt PTO opening location, and a 750,000-mile lube change interval are among some of the key features. The Endurant also offers a 5-year / 750,000-mile warranty, and a 3-year/350,000-mile clutch warranty.

“The 12-speed Endurant automated transmission is an important technological advancement for the Kenworth T680. Fleets and truck operators will benefit from its light weight, efficiency, reduced maintenance, and driver comfort,” said Patrick Dean, Kenworth’s chief engineer.
