Gearbox Calibration & Repair
Volvo, UD and Renault gearbox calibration and repair, carried out by experienced technicians. We diagnose the transmission electronically before any mechanical work and verify calibration results on the road.
What the Service Involves
- Electronic diagnosis of the transmission control module
- Gearbox calibration and adaptation resets
- Clutch and shift point recalibration
- Repair of identified transmission faults
- Road-test verification after calibration
Common Symptoms
- Harsh or jerky gear changes
- Transmission warning lights
- Gearbox stuck in one gear or limp mode
- Poor shifting after gearbox service or part replacement
Possible Causes
- Lost or outdated shift adaptations
- Worn clutches or shift components
- Faulty speed or pressure sensors
- Control module software or communication faults
How We Diagnose It
We scan the transmission module and review live data to distinguish calibration issues from genuine mechanical faults, so you don't pay for a mechanical overhaul when a calibration resolves the problem.
Why Professional Diagnosis Matters
Transmission calibration is brand-specific and data-driven. Incorrect calibration accelerates wear and creates new faults — our process is verified against live data and road tests.
