PACCAR Powertrain Experience
PACCAR engines share many design principles with other modern diesels — EGR, VGT turbochargers and SCR aftertreatment. We diagnose them with software, test components and repair the root cause. Because PACCAR trucks often run on long-haul routes, our roadside service helps when problems strike on the highway.
PACCAR Axles and Transmissions
We also service PACCAR axles and the TX-12 automated transmission, including clutch calibration after repairs.
