Based on the Endurant HD automated transmission, the new Endurant HD N model is optimized to integrate with Cummins natural gas engines and features new software functionality and calibrations, and a new diaphragm spring clutch from Eaton that is designed to meet the thrust bearing load requirements of natural gas engines and protect the engine for optimal performance.
The integration between the engine and transmission results in improved launch performance, improved low-speed maneuverability, and smoother shifts when compared to previous natural gas engines and automated manual transmission combinations.
The new Cummins natural gas integrated powertrain is designed for fleets looking to reduce their carbon footprint and help support their sustainability initiatives.
Eaton Cummins Automated Transmission Technologies has a broad portfolio of transmissions to help you get the job done. By answering a short series of questions about your truck and your route, we'll give you a couple of recommendations for heavy-duty automated transmissions that best fit your fleet's unique needs.
If there is a service issue, Endurant HD N uses Eaton 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 our technical experts. Unplanned downtime is reduced and quicker repair diagnosis gets you back on the road faster.
Like all Eaton Cummins automated transmissions, Endurant is backed by the support, solutions and expertise of the Roadranger network.
