Eaton Cummins Debuts Powerful Endurant Automated Transmission

| September 26, 2017


Eaton Cummins Automated Transmission Technologies has introduced the new Endurant 12-speed automated transmission – what the company describes as “the lightest, most efficient 1,850 lb.-ft. capable heavy-duty transmission.”

Designed for linehaul applications, Endurant weighs 105 pounds less than competitive automated manual transmissions (AMTs). Endurant is the first automated heavy-duty transmission to be introduced as part of the newly formed joint venture between Eaton and Cummins.

“Fleets will find that Endurant has been intelligently engineered from the ground up with features that protect your investment and make it easy to maintain,” 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.”

“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,” said Gerard DeVito, vice president, Technology, Eaton Vehicle Group.

Because reliability is key for linehaul fleets, the Endurant has been placed through over two million equivalent field test miles in extreme conditions including the high-heat of Death Valley, CA, and minus 40-degree temperatures in northern Minnesota.

More than 100 years of Eaton transmission experience has resulted in a host of Endurant features and benefits, including:

  • Internal electrical system routing that minimizes exposure and corrosion to wires and connectors for improved reliability;
  • A new smart prognostics feature provides clutch replacement notification to better plan maintenance scheduling;
  • An industry-exclusive transmission fluid pressure sensor notifies drivers of low oil levels to provide burn-up warranty coverage;
  • Smooth and intuitive shift strategies that enhance the operator’s driving experience;
  • Predictive shifting using look-ahead technology to execute shift decisions that improve fuel efficiency and provide additional driver comfort;
  • A standard, 8-bolt PTO opening that improves future resale value.

“With the lowest cruise RPM among competitive automated transmissions and the best overall ratios, Endurant is engineered to fully support the growing move to downspeeding to help save fuel,” added DeVito.

The Endurant also boasts:

  • 750,000-mile lube change intervals for linehaul applications, which is the industry’s longest and 250,000 to 450,000 miles longer than competitive models resulting in reduced downtime and maintenance costs;
  • A maintenance-free 430mm self-adjust clutch that requires no grease;
  • Endurant requires only 16 pints of oil, about half the amount of competitive models;
  • A replaceable input shaft sleeve allows for affordable and quick repair, while competitive transmissions require a costly and time-consuming full teardown.

Like all automated transmissions from Eaton Cummins, 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.

Endurant will be paired with the Cummins X15 Efficiency Series engine beginning in October for Peterbilt and Kenworth trucks.
