How Does Our Truck Transmission Repair Process Work? 

We follow this proven truck transmission rebuild process to get your heavy-duty unit back to peak performance.

Disassembly and Teardown

Technicians begin truck transmission repair by removing the external housing and disassembling internal components such as the valve body, pump, and drums. They carefully extract the gear sets and bands to prepare the unit for deep cleaning.

Cleaning and Inspection

We clean all metal parts in a high-temperature parts washer and inspect them for hot spots, burnt clutch material, or rounded gear teeth. This thorough inspection is vital for a successful heavy-duty transmission repair.

Component Replacement

Axle Spindle Technicians replace worn-out frictions, seals, and bushings with new parts from a high-quality rebuild kit. Replacing these small components ensures the semi-truck transmission repair lasts.

Reassembly and Testing

We carefully rebuild the internal sub-assemblies and reinstall them into the case while checking for proper clearances and end play. Once the pan and sensors are secured, the truck transmission repair is finished and ready for the road
