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 that my car's transmission needs repair?

Common signs that your car's transmission needs to be repaired include slipping gears, difficulty shifting gears, grinding noises, fluid leaks, and vibrations during gear changes. If you notice any of these symptoms, it's essential to have your gearbox inspected by our highly skilled technicians to avoid further damage.

What types of repairs can you carry out?

We provide several options to rectify a faulty transmission including gearbox replacement, rebuilds and reconditioning. At Service4Service, our specialist technicians only fit Original Equipment Manufacturer (OEM) or manufacturer warranty-approved parts and all repairs come with a 12-month guarantee.

What equipment do you use to repair a gearbox problem?

We can confidently diagnose any gearbox issues using the latest computer diagnostic equipment, repairing and replacing only the things that require it, using industry-approved tools and parts.

What is the difference between gearbox replacement and repair?

Gearbox repair involves fixing specific issues within the existing transmission, such as replacing worn components or addressing fluid leaks. Gearbox replacement means installing an entirely new transmission unit.

Why is my vehicle leaking oil?

Oil leaks can happen for a number of reasons, from wear and tear or broken seals to overfilled oil levels. Over time, your vehicle is at risk of general wear and tear and unfortunately, that includes your transmission and its related connections. Leaks should be fixed quickly, so it’s best to speak to a professional at Service4Service and get your car checked over.

Why is my car making a grinding noise?

The gearbox shafts need to be moving at the same speed in order to change gears smoothly and when this doesn’t happen, you’ll hear grinding. Modern cars tend to have a synchroniser ring to help keep both parts up to speed, but this can also go wrong from time to time, so it’s best to have things checked out.
