Yes. Our experienced technicians repair all major gearbox types, including manual, automatic, DSG, CVT, DCT and Powershift transmissions.

Gearboxes can fail for several reasons, including normal wear and tear, contaminated transmission fluid, overheating, poor maintenance, electrical faults or damaged internal components. Stop-start driving, towing heavy loads and ignoring early warning signs can all increase the likelihood of transmission problems.

Addressing small issues early can significantly extend the lifespan of your transmission.

Absolutely. Every gearbox repair begins with a comprehensive diagnostic assessment. We use specialist diagnostic equipment to check electronic systems, transmission sensors, control modules and mechanical components before recommending any work. This allows us to identify the root cause rather than simply treating the symptoms. Accurate diagnostics save time, reduce unnecessary costs and ensure repairs are targeted at the actual fault affecting your gearbox or transmission.

Driving with a faulty gearbox is not recommended. Small issues such as delayed gear changes or unusual noises can quickly develop into complete transmission failure if ignored. Continuing to drive may also cause additional damage to other drivetrain components, increasing repair costs. If you notice any gearbox warning signs, it's best to arrange an inspection as soon as possible. Early diagnosis often results in faster, more affordable repairs and helps keep your vehicle safe.
