Eaton Cummins Endurant

The Eaton Cummins Endurant transmission is a next-generation automated manual transmission (AMT) designed for heavy-duty trucks and vocational vehicles. Developed by Eaton, one of the leading manufacturers of commercial vehicle components, the Endurant series combines advanced engineering with cutting-edge technology to provide superior fuel efficiency, durability, and performance in demanding transportation applications. The Endurant transmission is designed to optimize powertrain performance, reduce operational costs, and enhance driver comfort, making it ideal for long-haul trucking, construction, and vocational applications.

Key Features:

• Automated Manual Transmission (AMT): The Endurant transmission is an automated manual transmission, combining the advantages of a manual transmission with the convenience of automation. This provides precise and smooth shifting without the need for a clutch pedal, helping reduce driver fatigue, improve driver productivity, and enhance vehicle control.
• 16-Speed Gearbox: The Endurant features a 16-speed transmission, offering an extensive range of gear ratios to meet the demands of different road conditions, driving environments, and load types. This wide range ensures optimal engine performance and efficiency across various terrains.
• High Torque Capacity: The Endurant transmission is designed to handle high torque outputs, making it suitable for heavy-duty applications. It can handle up to 2,050 lb-ft (2,780 Nm) of torque, providing the power needed for demanding trucking operations.
• Intelligent Shift Logic: The transmission utilizes Eaton’s ShiftSmart™ technology, which uses intelligent shift algorithms to adjust shifting based on load, terrain, and driving behavior. This helps maximize fuel efficiency by selecting the best gear for any situation.
• Fuel Efficiency: The Endurant transmission is designed with fuel savings in mind, utilizing advanced shifting logic to reduce engine load and maintain optimal engine speeds. The transmission’s ability to hold higher gears at cruising speeds helps improve fuel economy, resulting in lower operating costs.
• Durability and Reliability: Engineered for durability, the Endurant transmission is built to withstand heavy use and extreme operating conditions. Eaton uses high-strength materials and precision engineering to reduce wear, increase longevity, and minimize the need for maintenance. The transmission’s robust design makes it ideal for demanding commercial vehicle applications.
• Enhanced Driver Comfort: With its automated shifting system, the Endurant transmission significantly reduces driver fatigue by eliminating the need for manual gear changes. It allows drivers to focus on road conditions and traffic while the system handles gear selection automatically.
• Lightweight Design: Compared to previous-generation transmissions, the Endurant is significantly lighter, reducing overall vehicle weight and contributing to better fuel economy and payload capacity.
• Driver Modes: The transmission offers multiple driving modes, such as EcoMode and Performance Mode, which allow drivers to adjust the transmission’s behavior for optimal fuel efficiency or better acceleration and power when needed.
• Prognostics and Maintenance: The Endurant transmission is equipped with diagnostic and prognostic capabilities, which help fleet operators monitor performance, track wear, and predict maintenance needs. This system helps reduce unexpected downtime and lower maintenance costs.

Additional Features:

• ShiftSmart™ Technology: This feature uses an intelligent system to optimize gear selection based on driving conditions, such as road grade, load weight, and acceleration. The system ensures smooth and efficient shifting, which helps reduce fuel consumption.
• EcoMode: The Endurant transmission has a built-in EcoMode, which reduces engine RPMs and optimizes gear shifts for maximum fuel efficiency during highway driving, reducing fuel consumption and lowering total operating costs.
• Prognostics and Telemetry: The Endurant is compatible with Eaton’s Prognostics system, which continuously monitors the health of the transmission and provides alerts on potential issues before they result in significant problems. It can also integrate with telematics systems for fleet management, offering real-time data on performance, fuel efficiency, and maintenance schedules.
