Eaton Cummins Automated Transmission Technologies has produced its 500,000th Endurant transmission.
The unit was delivered to Werner, one of the first fleets to adopt the Endurant transmission following its debut in 2017, according to a news release.
A ceremony was held at the Kenworth Truck Plant in Chillicothe, Ohio, where a new Kenworth T680 equipped with the milestone transmission rolled off the assembly line. Eaton Cummins presented a commemorative plaque to Werner in recognition of their partnership and shared dedication to innovation.

“We are incredibly proud to reach this milestone and to celebrate it with Werner, a fleet that has been with us since the beginning of the Endurant journey,” Josh Mejeur, regional director, Eaton Cummins, said in the release. “This achievement reflects the strength of our partnerships and the value our customers see in the Endurant platform.”
“Werner has worked with Eaton for more than 40 years, and we were proud to receive the very first Endurant transmission,” said Scott Reed, Werner’s senior vice-president of maintenance. “This milestone reflects our shared commitment to innovation and providing our drivers with reliable, efficient equipment that delivers for our customers.”
The Endurant transmission family has grown to include multiple variants, including the Endurant HD, Endurant HD V, Endurant HD N, Endurant XD, Endurant XD Pro and Endurant XD N, serving both on-highway and vocational markets, the release added.
