Eaton Cummins Automated Transmission Technologies has announced its Endurant HD 12-speed automated transmission—the lightest, most efficient 1,850 lb.-ft.-capable heavy-duty transmission on the market—is now available at all major North American truck manufacturers, including International, Freightliner, Volvo, Peterbilt and Kenworth. 

The Endurant HD offers a number of advantages over competitive heavy-duty automated transmissions, including an industry-exclusive transmission fluid pressure sensor, the longest maintenance interval, and the best overall ratio coverage for low-speed maneuverability and downspeeding. 

“We work closely with our engine partners to deliver tailored solutions that meet their customers’ needs,” said Charles Masters, general manager, Eaton Cummins Automated Transmission Technologies. “In every case, the powertrain—the engine and transmission—is highly efficient and provides a low cost-of-ownership experience for the fleet.”

Engine and transmission powertrain combinations vary by truck manufacturer:

?The Endurant HD, paired with the Cummins X15 engine, is available in the Kenworth T680; Peterbilt 579; International LoneStar, LT Series and RH Series; Freightliner Cascadia; and Volvo VNL. 

?The Endurant HD and Cummins X12 powertrain, one of the lightest powertrains in its class, is available in the Freightliner Cascadia. 

?The Endurant HD and International A26 engine combination is available in the International LoneStar; LT Series; and RH Series.

?The Endurant HD and Detroit DD13 engine powertrain is available in the Freightliner Cascadia.

The standard Endurant HD transmission warranty is 5-years/750,000 miles for linehaul commercial vehicles. The Eaton-supplied clutch is covered by a 3-year/350,000-mile warranty. One-year and two-year extended protection plans are also available. Endurant HD’s maximum operating weight (GCVW) is 110,000 lbs. (49,895 kg); maximum horsepower is 510 HP (375 KW); and oil capacity is 16 pints (7.5L).
