Detroit--Detroit Diesel Corp. announced that the Detroit DT12 automated manual transmission is now available for the Freightliner Cascadia equipped with the Detroit DD13 engine.

The lighter-weight combination is well suited for regional haul, pick-up and delivery applications, say Detroit officials.
“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,” says Brad Williamson, manager, engine and component marketing for Daimler Trucks North America.
DT12 performance features include:
• 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.
