The Endurant HD is a lightweight, highly efficient transmission designed for superb driveability in on-highway applications. Sophisticated software allows the engine and transmission to work seamlessly, improving efficiency and performance. Smart features like a transmission fluid pressure sensor help protect the transmission from damage. In addition, the cooler-less design reduces the risk of cooler leaks and costly repairs. Predictive shifting uses look-ahead technology to execute shift decisions that improve fuel economy and driver comfort. Engineered with a twin-countershaft design for the most efficient delivery of engine torque, it’s capable of hauling up to 110,000 pounds (49,895 kg) Gross Vehicle Weight.
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.
The Endurant HD delivers an impressive combination of performance and efficiency.
The Endurant HD Series offers choices, so you choose what’s right for your fleet – direct drive and overdrive models, single and dual PTO mounts, diesel and natural gas engine compatibility, and unique software settings.
New for the Endurant HD series are Performance Goals which combine transmission shift points and clutch calibrations with unique software. This allows operators to easily tailor transmission performance to the demands of the job.
Achieving maximum performance requires a combination of strength and smarts. To get the most out of the Endurant XD series hardware, we use Gearlogic technology - a suite of intelligent features that improves performance, fuel efficiency, and driver confidence.
| FEATURES: | DESCRIPTIONS: |
|---|---|
| HILL START AID | Prevents unintended rollback or roll forward. When the grade exceeds the programmed threshold, the foundation brakes hold the truck for a controlled launch. It works when pointing uphill in drive or facing downhill in reverse. |
| AUTO NEUTRAL | Automatically switches the transmission into neutral once the parking brake is engaged to prevent potential movement of the vehicle. |
| ENGINE OVERSPEED PROTECTION | The transmission system up-shffts if necessary to prevent engine overspeed in drive, manual, and low modes. |
| ENHANCED ENGINE BRAKING | Downshifts the transmission to help slow the truck on long, steep descents and increase brake pad life. |
| LOAD-BASED SHIFTING | Selects appropriate starting gear and makes shift decisions based on grade, vehicle weight, engine torque, and throttle position. |
| URGE TO MOVE | Drivers simply release the brake pedal to automatically inch forward, similar to the feel of a passenger car. |
| CREEP MODE | Offers ultimate control to "creep" with a locked clutch at engine idle. Drivers can manually select different gears to fine-tune vehicle speed. |
| NEUTRAL COAST | Fuel-saving feature that disengages the driveline on slight downhill grades. |
| SMART GEAR SELECTION | The appropriate starting gear is selected and makes shift decisions based on grade, vehicle weight, engine torque, and throttle position - skip shifting when appropriate, making the most efficient changes based on those conditions. |
| PREDICTIVE SHIFTING | Uses look-ahead technology to execute shift decisions that improve fuel economy and driver comfort. |
The Endurant HD is backed by the support, solutions, and expertise of the Roadranger network—the most experienced and accessible drivetrain consultants in the business.
