Gearbox Repair Specialists in Bicester

Early gearbox issues often develop gradually rather than suddenly. You may notice hesitation when changing gears, slipping between gears, unusual noises such as whining or grinding, or vibration while driving. Automatic vehicles may feel jerky or slow to engage, while manuals may become harder to shift. Fluid leaks underneath the car or warning lights on the dashboard can also indicate transmission trouble. Addressing these signs early can prevent more serious internal damage.

In many cases, a gearbox can be repaired without the need for full replacement. This depends on the extent of internal wear or damage. Components such as clutches, solenoids, bearings, seals, or sensors can often be repaired or replaced individually. We always assess repair options first, as this can be more cost-effective and less invasive. Replacement is usually only recommended when damage is extensive or when repairs would not provide reliable long-term results.

Yes, we carry out repairs on both manual and automatic gearboxes at our Bicester facility. This includes traditional automatic transmissions as well as more complex systems such as DSG, CVT, DCT, and Powershift gearboxes. Each system has unique components and operating principles, which is why our technicians specialise specifically in transmission work. This focused expertise allows us to diagnose faults accurately and apply the correct repair approach for each gearbox type.

The length of a gearbox diagnostic depends on the nature of the problem and the vehicle type. In many cases, initial diagnostics can be completed within the same day. This typically includes electronic fault-code checks, mechanical inspection, fluid condition assessment, and road testing where appropriate. More complex issues may require extended testing to pinpoint intermittent or internal faults. Once diagnostics are complete, we provide a clear explanation of the findings and recommended repairs.

Yes, all gearbox repairs are covered by a 12-month warranty for added reassurance. This warranty reflects our confidence in the quality of our workmanship and the parts we use. It covers the repaired components under normal use conditions and provides peace of mind that your vehicle is protected after the repair is completed. Full warranty details are explained clearly before work begins, so you know exactly what is included.

Low or degraded transmission fluid is one of the most common causes of shifting issues. Fluid plays a critical role in lubrication, cooling, and hydraulic pressure within the gearbox. When levels are low or fluid quality is poor, gears may slip, shifts can become delayed or harsh, and internal components can overheat. Left unresolved, this can cause significant damage. Regular fluid checks and servicing help maintain smooth and reliable gearbox operation.

Yes, our technicians are trained to work on modern vehicles, including those with advanced transmission systems found in newer and hybrid models. Modern gearboxes often integrate electronic controls, sensors, and software that require specialist diagnostic tools and expertise. We stay up to date with evolving transmission technology to ensure accurate diagnosis and correct repair methods, allowing us to service a wide range of contemporary vehicles safely and effectively.

A gearbox rebuild involves dismantling your existing transmission, replacing worn or damaged internal components, and reassembling it to manufacturer specifications. A replacement involves fitting a reconditioned or new gearbox unit instead. Rebuilds are often more cost-effective and retain the original casing, while replacements may be recommended if damage is extensive. We assess each case individually and explain which option offers the best balance of reliability and value.

Some gearbox faults will trigger a dashboard warning light, such as an engine management or transmission warning indicator. However, not all issues generate fault codes, particularly mechanical wear or fluid-related problems. This is why physical inspection and road testing are often just as important as electronic diagnostics. If your vehicle feels different to drive, it’s worth having it checked even if no warning lights are present.

We understand that gearbox repairs can be unexpected, which is why finance options may be available to help spread the cost. Interest-free plans can allow you to manage payments over a set period without financial strain. Availability depends on the repair and eligibility criteria. We’re happy to discuss finance options once diagnostics are complete and a repair plan has been agreed.
