Part of the Detroit Diesel complete powertrain offering, the DT12 combines the operational ease of an automatic with the efficiency of a manual transmission, resulting in enhanced fuel economy, vehicle performance and safety. Available in the Freightliner Cascadia®, the DT12 maximizes fuel efficiency for line-haul/long haul operations. Adding to the transmission’s overall economy is its lightweight design, which offers additional payload because of its aluminum housing and single counter shaft. The DT12 improves slow-speed maneuvering capabilities without compromising high road speed efficiency. The 12-speed, direct- or over-drive automated manual transmission combines a traditional manual gearbox with high-speed, computer-controlled shift and clutch actuators that automatically and seamlessly select the right shift pattern and perfect clutch engagement for fuel economy and engine power. The DT12’s creep mode simulates a torque converter to improve low speed maneuverability for parking, docking, heavy traffic and other low speed situations.
