Detroit announces DT12 Vocational series heavy-duty truck transmission

Detroit announces new DT12 Vocational series transmission in the Western Star 49X

As part of the launch of the new Western Star 49X, Daimler Trucks North America debuted the Detroit DT12 Vocational series of automated manual transmissions.

Available as either the DT12-V or the DT12-VX and rated up to a GCWR of 330,000 lbs, the DT12 Vocational series was validated in over 35 million miles of testing to deliver performance and durability and can be mated to the Detroit DD15 Gen 5 engine or Detroit DD16 engine, DTNA said. Both engines come equipped with Detroit Connect Virtual Technician remote diagnostic services.

The DT12 Vocational series of transmissions include side PTO capabilities that allow for added flexibility. A Rock-Free Mode allows the 49X to free itself from wheel stuck situations, an Off-Road Mode enables smooth driving on extreme terrain, like logging roads and rock quarries, Power Launch which provides powerful takeoffs while protecting the clutch and driveline, and a Paver Mode which allows the truck to shift from Neutral to Drive without depressing the brake pedal when pulling away, the OEM detailed.
