TEST: Tow Haul Mode vs Pacbrake's PRXB

As the graph comparison shows, selecting the Allison transmission’s tow/haul mode when reducing speed provides approximately 150 retarding horsepower. In the same mode, with the addition of a Pacbrake PRXB, the retarding ability is almost doubled, providing the most effective speed reduction possible without the need for service brakes. Allison transmissions will automatically downshift to attain higher RPM to aid in retarding, but with a Pacbrake PRXB, higher RPM is not as critical due to the unique modulation design.
