Our Transmission Rebuild Process
Every transmission overhaul follows a structured process:
Full strip-down inspection to identify wear, damage and root cause of failure.
Inspection & Diagnosis
Gear tooth inspection, clutch pack measurement, bearing and seal evaluation, shaft and housing checks.
Measurement & Assessment
Replacement of worn bearings, seals, friction plates, clutch components and damaged gearing as required.
Component Replacement
Careful reassembly to manufacturer specifications with final testing to ensure correct operation.
We focus not only on repairing the failure, but also identifying contributing factors to prevent repeat issues.
Reassembly & Testing
When Should a Transmission Be Rebuilt?
Transmission rebuilds are recommended when:
