Eaton Cummins joint venture unveils its first automated transmission
Eaton Cummins Automated Transmission Technologies has unveiled the first automated heavy-duty transmission to be introduced as part of the newly formed joint venture between Eaton and Cummins.
The new Endurant 12-speed automated transmission is the lightest, most efficient 1,850 lb.-ft. capable heavy-duty transmission, the companies said in a joint statement. Designed for linehaul applications where weight savings and efficiency can add to a fleet’s bottom line, Endurant weighs up to 105 pounds less than competitive automated manual transmissions (AMTs).
“We are excited to introduce our customers to this game-changing transmission. With a sophisticated communication system between the engine and transmission software, Endurant promises to deliver industry-best performance and reliability, fuel efficiency, reduced maintenance, and driver comfort features,” said Scott Davis, general manager, Eaton Cummins Automated Transmission Technologies.
“It is important to note that Endurant is not an automated variant that has been adapted from a manual transmission,” said Gerard DeVito, vice president, Technology, Eaton Vehicle Group. “Endurant was designed, engineered and created from a clean sheet to be an automated transmission, not simply an update to an AMT, allowing us to optimize the transmission’s weight, dimensions and features.”
Both companies developed an extensive component and complete vehicle testing program to put Endurant through extreme conditions at the Eaton Proving Grounds in Marshall, MI, in the high-heat of Death Valley, CA, and minus 40-degree temperatures in northern Minnesota. A testing regimen that resulted in more than two million equivalent field test miles.
Endurant will be paired with the Cummins X15 Efficiency Series engine beginning in October for Peterbilt and Kenworth trucks. The transmissions developed by the joint venture between Cummins and Eaton are manufactured in San Luis Potosi, where both companies operate production facilities.
