Leak Tight Test

Here, air pressure and oil are used to ensure our assembled transmissions have no leaks. But wait, there’s more! Even after the computer says everything “checks out”, we continue to perform quality checks by manually disassembling a set number of transmissions on a regular basis for an added level of quality confirmation.


Power Take Off

Cement mixers, dump trucks and other vehicles that need moving parts in addition to their powertrain can now trust in Detroit™ transmissions equipped with Power Take Off (PTO) … a new offering in 2017 in partnership with Italy’s Hydropart®.

See DT12 Power Take Off Brochure


Gentle Giant

So monstrous we had to give it its own monster name: Godzilla is how we affectionately refer to the world’s largest one-piece robot, built specifically to lift our nearly fully-assembled, 620-pound transmissions and gently turn them on their side for the installation of crucial electronic components.


Give Me The Works

This single screen provides a complete snapshot of the DT12™ line in one centralized location. Its contents indicate the status of work at each individual station, to not only keep everyone up to speed on progress, but also indicate where faults need to be resolved. We constantly monitor these screens to make sure that the manufacturing line runs smoothly.

Transmission Dyno-Testing

Transmission Dyno-Testing

Detroit is the only manufacturer that “hot tests” 100% of its transmissions, which simulates driver on-the-road usage. Each transmission is “taught” to cycle through all its gears, and then testing is conducted to ensure the transmission performs all functions perfectly. That means every transmission that leaves our facility is literally tested “tried and true,” giving you remarkable piece of mind.

Additional Information Related To This Image:

Transmissions Ready To Roll

Our state-of-the-art dyno testing program stores manufacturing information into the “brain” of each of our transmissions. This allows us to always trace back to each transmission build, keeping our team and processes accountable. Then we hot test every possible transmission function, including reverse, ramping, railing and splits. When your transmission is delivered to you, you know it’s up for the job.
