Dodge Gearbox Repair in Fontana
For Dodge and Ram work trucks, the transmission is where the living gets earned — and few transmissions work harder than those in the Ram 5500s, chassis cabs and crane trucks we sell and service ourselves. Dodge and Ram transmissions and gearbox assemblies are rebuilt in-house at our Fontana shop, and our gear manufacturing capability turns a discontinued gear from a dead end into just another line item.

Driveline work for Ram and Dodge
Transmissions, automatic and manual alike, are rebuilt — torn down, measured, and fitted with renewed or manufactured clutch packs, bearings, gears and shafts — and transfer cases, differentials and the surrounding driveline hardware are covered too. Cummins-powered trucks are home turf here, and the whole truck is serviced in the same building, from the engine out to the axle.

Questions customers ask us
Are Ram 5500 transmissions rebuilt here?
Yes — transmissions from Ram chassis cabs are regular work here, and so is the rest of the truck’s driveline.
Can gears be obtained for an older Dodge transmission?
When a gear has been discontinued, our shop manufactures it — that capability is precisely why older Dodge work trucks end up here.
