Eaton Cummins Automated Transmission Technologies unveiled its first collaborative effort, the Endurant, a 12-speed automated transmission at the inaugural North American Commercial Vehicle Show in Atlanta.

This is the first product announcement since the joint venture between Eaton and Cummins launched Aug. 1., said Scott Davis, general manager at Eaton Cummins Automated Transmission Technologies.

Under the terms of the agreement, Eaton will receive $600 million in cash from Cummins for 50 percent interest in the joint venture.

“It is the lightest, most efficient product on the market,” Davis said.

The transmission was “designed for linehaul applications where weight savings and efficiency can add to a fleet’s bottom line,” Eaton Cummins said.

“Endurant was designed, engineered and created from a clean sheet to be an automated transmission, not simply an update to an (Automated Manual Transmission), allowing us to optimize the transmission’s weight, dimensions and features,” said Gerard DeVito, vice president of technology at Eaton Vehicle Group.

Eaton Cummins said it put the Endurant through an extensive component and complete vehicle testing program in extreme conditions, including the Eaton Proving Grounds in Marshall, Mich., scorching temperatures in Death Valley, Calif., and minus 40-degree temperatures in northern Minnesota.

“This grueling testing regimen resulted in more than 2 million equivalent field test miles,” the company said.

Another key feature to addressing costly and time-consuming maintenance requirements is the lube change intervals for linehaul applications. The Endurant has a lube change interval range of 750,000 miles, the industry’s longest, and between 250,000 to 450,000 miles longer than its competitors. The transmission also has a greaseless 430mm self-adjust clutch that is maintenance free. The transmission requires only 16 pints of oil, almost half that of its competitors.

Endurant is available with IntelliConnect, “a telematics capable system that provides near real-time monitoring of vehicle fault codes, prioritizes the critical events and provides accurate and comprehensive action plans by technical experts at Eaton,” according to Eaton Cummins.

The Endurant will be paired with the Cummins X15 Efficiency Series Engine, which will start production Oct. 16. They will be available on the Kenworth T680 and the Peterbilt 579.
