Your gearbox and differential carry the engine's power to the wheels. When they start making noise or misbehaving, early attention usually costs far less than waiting for a failure. We diagnose and repair manual gearboxes, look after automatic transmissions, and work on differentials and 4x4 transfer cases.
Automatic faults often start electronically, so we begin with a diagnostic scan before deciding on the next step.
Symptoms to watch for
- Whining or humming that changes with speed
- Grinding or crunching when changing gear
- Jumping out of gear
- Automatic gearbox slipping, flaring or shifting late
- Delayed engagement when selecting drive or reverse
- Clunks when pulling away or on and off the accelerator
- Oil leaks under the middle or rear of the vehicle
What we do
- Gearbox and differential oil changes to manufacturer specs
- Oil seal and leak repairs
- Automatic transmission fluid service where specified
- Gearbox removal and refitting, and repair or exchange
- Differential inspection and repair
- 4x4 transfer case checks
Fluid matters
Gearbox and diff oil is often called 'lifetime' fluid, but heat and heavy use break it down. If you tow, carry loads or drive off-road, ask us about changing it sooner.
Common questions
Should automatic gearbox fluid be changed?
Many manufacturers specify a change at set intervals. We check your schedule and advise.
Is a whining diff dangerous?
It is a sign of wear that will get worse. Have it inspected before it fails.
Can you repair my gearbox or do I need a new one?
It depends on the fault. We diagnose it and give you the options.
Do you work on 4x4s?
Yes, including differentials and transfer cases.
