Detroit unveils lighter DT12-VL automated vocational transmission

Detroit has introduced the DT12-VL, the latest member of its automated manual transmission lineup, purpose-built for heavy-duty vocational applications where payload is paramount.

The new model delivers enhanced off-road performance, improved drivability, and a 125-pound weight reduction compared to the DT12-V, ensuring operators get maximum payload without compromising durability.

Key specifications

• Torque rating: 1,650 lb-ft

• Rear PTO

• Gear ratio range: 11.67 (1st gear) to 0.78 (top gear)

• 12 forward speeds, up to 4 reverse speeds

• Supports gross combination weights up to 80,000 lb

Aaron Scates, vice president of vocational and medium-duty market development for Daimler Trucks North America, said the DT12-VL “is a testament to our commitment to vocational customers and our ability to innovate on proven solutions.”

Built for real-world challenges

Detroit’s new transmission comes equipped with three standard features designed to enhance control and performance:

• Off-Road Mode keeps gears longer for better momentum on rough terrain.

• Rock Free Mode modulates the clutch to help free stuck vehicles while reducing driveline stress.

• Paver Mode allows seamless shifts from Neutral to Drive without brake input, ensuring smooth paving operations.

With the DT12-VL, Detroit continues to push boundaries in vocational trucking technology, combining strength, precision, and efficiency in a lighter package.
