Repair or replace a manual gearbox
Noisy bearings, difficult selection or a gear that will not stay engaged can require closer investigation. We assess the fault and discuss repair, reconditioning or replacement according to the gearbox and the damage found.
Clutch and linkage faults are considered too, so we do not assume every shifting problem is internal gearbox damage.
Automatic gearbox servicing
We can assess automatic transmission servicing, including oil changes on suitable BMW, Mercedes-Benz and other vehicles. The gearbox type, fluid specification and required procedure determine the work.
Call with the registration to confirm suitability before booking; an oil change does not guarantee a cure for an existing internal fault.
Agree the gearbox assessment and cost
Quote after assessment
Your quote depends on the vehicle, parts and work needed. Call with your registration and symptoms so we can explain the assessment and agree the repair cost.

Some symptoms arise elsewhere in the drivetrain. We can investigate the relevant components and explain which repair is appropriate rather than quote for a gearbox by guesswork.
Identify the transmission before choosing a service
Automatic, dual-clutch, CVT and conventional manual gearboxes have different requirements. Before arranging a service, we confirm:
- The transmission fitted to the vehicle.
- The fluid specification and level-setting procedure.
- Any filters and temperature checks required by that unit.
- The previous gearbox-service records, where available.
A generic fluid change or an additive is not a reliable diagnosis for slipping, harsh engagement or a transmission warning.
Describe the fault as precisely as you can
Tell us whether the problem happens when selecting a gear, moving away, changing up or slowing down. Note any difference between a cold and warm car, and whether there is a leak, vibration or warning message.
A fault can involve controls, mounts, driveshafts or the clutch as well as internal gearbox parts. We discuss the assessment and the scope of a repair or replacement before work starts.
Frequently asked questions
Do you recondition manual gearboxes?
Yes. Repair or reconditioning options depend on the unit, damage and parts availability.
Can you service my automatic gearbox?
Call with the registration and gearbox details. We confirm whether we can carry out the required oil-service procedure.
Is every automatic repair available in-house?
The scope depends on the transmission and fault. We confirm what we can undertake after assessment.
