DETROIT DT12 VOCATIONAL TRANSMISSIONS
Detroit has taken the millions of hours of reliability of the DT12® automated manual transmission and engineered it into an all-new model designed and tested with vocational customers in mind -- the Detroit DT12-V. Now your operators can enjoy the rugged performance of the DT12 in pavers, dump trucks, logging trucks and more, no matter what remote corner of the world they’re working in.
Vocational Features
A wider overall ratio for improved startability and low speed maneuverability with a new planetary gear set design for greater input torque and GCW limits with improved durability.
Staying in drive and using the accelerator pedal gives the ability to break free from wheel-stuck situations and related downtime.
Specifically designed to take on off-road driving conditions with optimized shift maps for extreme road conditions.
The DT12-V enables a constant flow to paving machines by shifting from Neutral to Drive without depressing the brake pedal.
The DT12-V’s bottom PTO provides dependable performance and, when combined with the rear PTO, offers dual PTO usage that further increases job flexibility and application coverage.
Automatically increases engine speed up to 1,200 RPM during launch for smooth, powerful takeoffs with heavy loads while protecting the clutch and driveline.
Available Transmissions
To help you build exactly the truck you need, we offer a full range of both Eaton Fuller and Allison transmissions. To spec the exact transmission you need, find your nearest Western Star dealer.
