Dodge Gearbox Repair in Fontana
Dodge and Ram work trucks earn their living through their transmissions — and Ram 5500s, the chassis cabs and crane trucks we sell and service ourselves, work theirs harder than most. Our Fontana shop rebuilds Dodge and Ram transmissions and gearbox assemblies in-house, with the gear manufacturing capability that turns a discontinued gear from a dead end into a line item.

Ram and Dodge driveline work
Automatic and manual transmissions rebuilt — teardown, measurement, clutch packs, bearings, gears and shafts renewed or manufactured — plus transfer cases, differentials and the driveline hardware around them. Cummins-powered trucks are home turf: we service the whole truck, engine out to axle, in the same building.
