Truck drivetrain system DT12 series

RUGGED, RELIABLE AND READY TO WORK. Performance and durability under extreme conditions. That’s what the Detroit® DT12® Vocational Series transmissions bring to every job. Our two vocational models – the DT12-V and DT12-VX – are now available in the Western Star 47X, Western Star 49X and Freightliner Plus-series trucks. No road, trail or work site is too extreme for these sturdy, reliable Detroit transmissions to handle. • New vocational features • Increased application coverage • Ease of operation for driver comfort RAISING THE BAR ON DURABILITY: THE DETROIT DT12 VOCATIONAL SERIES • Large, robust gears for tough jobs. The DT12-V and DT12-VX feature large, robust gears that allow for increased gross combination weight (GCW) and input torque. Thousands of hours of rigorous testing have made the DT12-V and DT12-X transmissions purpose-built to take on rugged environments. • An improved oil system design. A new oil pump provides a more continuous flow of oil at all speeds and operating conditions. Its bottom-mounted oil intake also allows oil to be picked up at the lowest level and sprayed onto the gear mesh, ensuring ample lubrication in tough conditions—and less parasitic loss due to oil splash. • Enhanced thermal management for greater reliability. The oil cooler’s adaptive bypass valve maintains oil at an optimal temperature for any running application. This cools oil when it’s needed and bypasses when it’s not.
