Detroit DT12 Transmission

The Detroit DT12 is an advanced, automated manual transmission (AMT) designed for heavy-duty trucks and commercial vehicles. Developed by Detroit, a brand known for its engineering excellence, the DT12 combines the benefits of a manual transmission with the convenience of an automated system, offering improved fuel efficiency, reliability, and driver comfort. It is engineered to handle the demands of long-haul and vocational trucking, making it suitable for a wide range of applications, including freight hauling, construction, and other demanding industries.

Key Features:

• Automated Manual Transmission (AMT): The Detroit DT12 is an electronically controlled, automated manual transmission, meaning it uses a manual gearbox but automates the shifting process. This offers the fuel efficiency of a manual transmission while reducing driver fatigue and the likelihood of shifting errors.
• 12-Speed Gearbox: The DT12 comes with a 12-speed gearbox that provides a wide range of gear ratios, offering optimal engine power utilization and fuel efficiency in varying driving conditions.
• Torque Capacity: The Detroit DT12 is designed to handle up to 1,850 lb-ft of torque, making it suitable for the most demanding heavy-duty applications, such as long-haul trucking and heavy freight hauling.
• Intelligent Shift Logic: The transmission features advanced shift logic that adjusts the shifting pattern based on vehicle load, grade, and driving conditions. It ensures smoother gear changes and maximizes fuel efficiency by choosing the optimal gear.
• Gradeability and Launch Assist: The DT12 features Hill Start Aid and Gradeability Assist, which helps prevent rollback on inclines and ensures smoother starts on grades. This feature is particularly helpful for drivers operating in mountainous terrain or on steep inclines.
• Fuel Efficiency: The Detroit DT12 is optimized for fuel economy, with its automated shifting system allowing the engine to operate in the most efficient range for longer periods. The shift logic also adapts to the driving style and terrain, helping reduce fuel consumption.
• Driver Comfort: The automated transmission removes the need for manual gear shifting, which reduces driver fatigue, especially in stop-and-go traffic or during long-haul driving. The system is designed to smoothly shift gears, providing a more comfortable driving experience.
• Durability: The DT12 is built with heavy-duty components and is engineered for long-lasting performance in demanding environments. Its design minimizes wear on the transmission, improving reliability and reducing the need for maintenance.
• Integrated with Detroit Powertrain: The DT12 is designed to work seamlessly with Detroit engines and axles, offering optimized powertrain performance. This integration helps maximize fuel efficiency and overall vehicle performance, reducing maintenance and downtime.

Additional Features:

• Detroit Connect: The DT12 can be integrated with Detroit Connect, an advanced telematics system that provides fleet managers with real-time data on transmission performance, fuel economy, and maintenance needs.
• Prognostics and Maintenance: The DT12 includes a built-in prognostic system that monitors the transmission’s health and predicts potential issues before they become serious, helping fleet operators minimize downtime and reduce maintenance costs.
• Driver Mode Selection: The DT12 allows the driver to select from different driving modes, such as Eco, Performance, and Manual modes, providing flexibility depending on the driving conditions and load requirements.
• Self-Learning: The DT12 transmission learns the driver’s shifting style and optimizes its shifting pattern accordingly, leading to smoother operation over time.
