@NACV: Eaton-Cummins JV Unveils Endurant Transmission

Eaton Cummins Automated Transmission Technologies, the 50/50 joint venture between Eaton and Cummins, Inc., has introduced its first product, a new 12-speed automated transmission that the company called the lightest, most efficient 1850 lb. ft.-capable heavy-duty transmission on the market. The new gearbox was unveiled at the inaugural North American Commercial Vehicle (NACV) show in Atlanta.

Designed for linehaul trucking applications where weight savings and efficiency can add to a fleet’s bottom line, the Endurant transmission weighs up to 105 lb. less than competitive automated manual transmissions (AMTs).

The Endurant transmission’s maximum gross combined vehicle weight (GCVW) capacity is 110,000 lb., with an engine input capacity of 510 hp. It will be paired with the Cummins X15 Efficiency Series engine beginning in October for Peterbilt and Kenworth trucks.

“We are excited to introduce our customers to this game-changing transmission,” said Scott Davis, general manager, Eaton Cummins Automated Transmission Technologies. “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.”

“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.”

Endurant transmission features include:

– Internal electrical system routing designed to minimize exposure and corrosion to wires and connectors for improved reliability.

– A new prognostics feature that provides clutch replacement notification to better plan maintenance scheduling.

– A transmission fluid pressure sensor engineered to notify drivers of low oil levels to provide burn-up warranty coverage.

– Shift strategies that include predictive shifting using look-ahead technology to execute shift decisions and are programmed to improve fuel efficiency and provide additional driver comfort.

– A standard, eight-bolt PTO opening that the company said improves future resale value.

Like all automated transmissions from the Eaton Cummins joint venture, Endurant is available with IntelliConnect, a telematics capable system engineered to provide near real-time monitoring of vehicle fault codes, prioritize the critical events and provide accurate and comprehensive action plans by Eaton service personnel.
