Gearbox Diagnostics

A gearbox rarely fails without warning. Slipping gears, delayed engagement, grinding noises and transmission warning lights are all signs that something needs attention. The sooner a fault is identified, the lower the repair cost is likely to be.

Our technicians use the latest specialist diagnostic equipment to find the root cause of any gearbox fault quickly and accurately. Every diagnostic includes a transmission fluid check, live gear shift analysis, fault code reading and a full sensor and solenoid assessment giving us a clear picture of what is wrong before any repair work is recommended.

Whether your vehicle has a manual, automatic, DSG, CVT or dual-clutch gearbox, we carry out a full diagnostic on every job. We never recommend repairs without first identifying the fault.

Gearbox Rebuild Specialists

A gearbox rebuild is the right solution when internal damage is too widespread for a targeted repair. Rather than replacing the whole unit, our technicians strip the gearbox down completely, inspect every component and replace anything that is worn or damaged returning it to a reliable, fully functioning condition at a fraction of the cost of a new unit.


Every rebuild at Service4Service follows a structured process:

  • Diagnosis - full diagnostic to confirm a rebuild is the correct course of action
  • Disassembly - complete strip down of the gearbox unit
  • Inspection - every component checked against manufacturer tolerances
  • Parts replaced - worn gears, bearings, seals and clutch packs replaced with OEM-grade parts
  • Cleaning - all casings and retained components cleaned before reassembly
  • Reassembly - precise reassembly to manufacturer specification
  • Full testing - performance and pressure testing before the vehicle is returned

All gearbox rebuilds come with a 12-month guarantee*

Frequently Asked Questions

Understanding your vehicle's maintenance needs, and addressing issues promptly are key to maintaining your car's performance and reliability. If you have specific questions about your vehicle or a repair issue, don't hesitate to call Service4Service on 0808 164 0418 for guidance.

What are the signs my automatic gearbox needs repair?

Common signs include slipping between gears, hesitation or delayed engagement, whining or grinding noises, a transmission warning light, and fluid leaks. Catching these early usually keeps the repair cost down, so it's worth getting your gearbox inspected as soon as you notice them.

What types of repairs can you carry out?

We repair, rebuild, recondition and replace automatic gearboxes, including DSG, CVT and dual-clutch transmissions. Every repair uses genuine manufacturer-approved parts and comes with a 12-month guarantee on parts and labour, backed by 20,000+ completed gearbox rebuilds.

What's the difference between an automatic gearbox repair and a replacement?

A repair fixes specific faults within your existing gearbox, such as worn components or fluid leaks. A replacement means fitting an entirely new transmission unit. We always assess for the more cost-effective repair first, and only recommend replacement when repair won't restore reliable performance.

Why is my automatic gearbox leaking oil?

Gearbox oil leaks are usually caused by worn seals, general wear and tear, or an overfilled fluid level. Left unfixed, a leak can lead to more serious internal damage, so it's best to have it checked by a specialist as soon as you notice one.

Why is my automatic gearbox making a grinding or whining noise?

Grinding or whining usually means internal components- such as the gears or synchroniser ring- aren't moving in sync or are starting to wear. It's a common early warning sign, so it's worth having it diagnosed before it turns into a bigger repair.

Do your automatic gearbox repairs come with a warranty?

Yes. Every automatic gearbox repair and rebuild comes with a 12-month/12,000 miles guarantee on parts and labour. We only fit genuine manufacturer-approved parts, and all work is carried out in a way that protects your existing manufacturer's warranty.

Can I keep driving with a gearbox warning light on?

It's not advisable. A gearbox warning light means the diagnostic system has flagged a fault, and continuing to drive risks turning a minor repair into a much bigger one. It's best to have it checked by a specialist as soon as possible.

Why has my automatic gearbox gone into limp mode?

Limp mode is a safety feature that activates when the transmission control system detects a fault, restricting your car to lower gears and reduced speed to prevent further damage. Common causes include low transmission fluid, a faulty solenoid, or a wiring fault. It's best to have it diagnosed rather than keep driving on it.

Why is my automatic gearbox jerking or hesitating when changing gear?

Jerking or hesitation usually points to worn clutch packs, a failing solenoid, or degraded transmission fluid. It's especially common in DSG and dual-clutch gearboxes. Left undiagnosed, it typically gets worse, so it's worth having it checked before it leads to a bigger repair.
