DT12 TRANSMISSION – WESTERN STAR
MAXIMUM FUEL EFFICIENCY. FRONT TO BACK.
- Integrated communications benefits: The DT12 transmission links engine to axles, and communicates with every model in the Detroit engine lineup on an integrated electronics network to share damage-reducing information such as clutch overloading and driveline protection.
- Super-finished gears: Tightly-spaced 12-speed gearing, now with “super-finished” gears in the new DT12, improves low-speed manoeuvrability, making the Detroit powertrain not only strong and efficient, but also smooth and safe to operate as well.
Intelligent powertrain management (IPM)*: The DT12 uses GPS technology and information from a topographical map to manipulate both engine and transmission functions, taking advantage of the truck’s surroundings. IPM refines the parameters of this technology, making the truck even more capable of utilising its surroundings for maximum fuel efficiency.
Transmission benefits: The DT12’s gearing, along with eCoast, are integrated with Detroit’s DD13 and DD16 engines for optimised fuel economy.
* Vehicle specification may vary by market and some features may be optional equipment.

A proud tradition of building engines with strength, quality and dependability began for Detroit® in 1938, when it was known as the General Motors (GM) Diesel Division. The heavy-duty, on-highway Series 71 engine was used extensively in military and road-building and was followed by the Series 53 model, another powerhouse with wide-ranging applications.

Performance on demand.
- Off-Road Mode features shift maps that give you peak performance on any terrain.
- Rock-Free Mode helps you avoid wheel-stuck situations by using the accelerator to rock the vehicle free.
- Paver Mode allows a dump truck to shift from neutral to drive without pressing the brake pedal while moving away, ensuring a steady flow to the paving machine.
- The Power Launch feature automatically increases engine speed to 1,200 RPM to ensure smooth, powerful take-offs with heavy loads—all while protecting the clutch and driveline.
