Detroit DT12 Automated Manual Transmission now available


Detroit Diesel Corporation (Detroit) has announced that its Detroit DT12 Automated Manual Transmission is now available for the Freightliner Cascadia equipped with the Detroit DD13 engine.

Detroit offers a complete line of heavy duty diesel engines, axles and transmissions for the commercial transportation industry in both the on-highway and vocational markets. Its products are sold and serviced through a network of more than 800 locations throughout North America.

Detroit is a part of Daimler Trucks North America (DTNA). DTNA produces and markets Class 4 to 8 trucks and is a Daimler company, the world's leading commercial vehicle manufacturer

The DT12 combines the operational ease of an automatic with the efficiency of a manual transmission, says Brad Williamson, manager - engine and component marketing for DTNA. Featuring a lighter weight, the DT12 paired with the DD13 engine is ideally suited for regional haul, pick-up and delivery applications.\

The DD13 is a 12.8-liter, six-cylinder, in-line engine  offered in output and torque variants from 350 to 450 hp and 1,350 to 1,650 ft/lbs.

“Because of the type of routes that they run, which often involve a lot of stop and go operations, our regional haul customers are seeking ways to extend fuel economy,” he says. “Together, the DT12 and the DD13 provide a smart, productive solution that boosts efficiency.”

The DT12 has performance features that further maximize efficiency, such as creep mode, which modulates the clutch to improve low-speed maneuverability, making backing up to a loading dock or maneuvering through tight city traffic easier. Skip Shift, which automatically skips gears, enables the transmission to run through lower gears faster to achieve cruising speed sooner.

The DT12 comes standard with a 5-year/750,000-mile warranty and a 3-year/350,000-mile warranty on the clutch.

The Detroit Customer Service network provides immediate access to maintenance information. It has hundreds of authorized locations in the United States and Canada.
