Frequently asked questions about a gearbox repair

If your clutch has gone, you may have a problem trouble shifting gears or a soft or spongy clutch pedal. It might not even move when in gear!

Gearbox issues, on the other hand, show themselves with grinding noises, difficulty staying in gear, or leaking fluid. Both issues affect your gear shifting but come from different parts of the transmission system.

A gearbox specialist is a mechanic who’s an expert in diagnosing, repairing, and replacing gearboxes. They have training and experience dealing with many types of gearboxes, including manual, automatic, and semi-automatic systems. Talking to a specialist makes sure that any gearbox issues you may have are accurately diagnosed and repaired to the best standard.

Yes, many damaged gearboxes can be repaired. How damaged it is dictates how repairable it is. Small issues like worn seals or bearings can often be fixed. Severe damage might mean a complete rebuild or replacement. A professional mechanic can see the damage and tell you the best course of action.

Common signs of a faulty gearbox include:

  • Grinding or whining noises.
  • Difficulty changing gears.
  • Leaking transmission fluid.
  • A burning smell from the transmission area.
  • The car slipping out of gear or not staying in gear.

If you notice any of these symptoms, it’s best to get your gearbox seen by a professional.

The gearbox transfers power from the engine to the wheels. This allows your car to move at different speeds. It adjusts the engine's power output to the wheels and makes sure the engine runs well at various speeds.

Mechanics use several methods to find gearbox issues:

  • Visual inspection: Checking for obvious signs of damage or leaks.
  • Test drive: Watching the car’s performance while driving.
  • Diagnostic tools: Using scanners to read error codes from the car’s computer.
  • Fluid analysis: Checking the condition and level of transmission fluid.

These methods help pinpoint the problem.

A DSG (Direct-Shift Gearbox) is a type of automatic transmission. It uses two clutches for faster and smoother gear changes. As it combines the ease of an automatic with the performance of a manual gearbox, it’s popular in many modern vehicles.

Whether a gearbox repair is covered by warranty depends on your policy. Manufacturer warranties often cover gearbox repairs in a certain period or mileage. Extended warranties and aftermarket policies may also provide you cover. Check your warranty details or talk to your provider for more information.

Most standard car insurance policies don’t cover gearbox repairs unless the damage is due to an insured event like an accident. Mechanical breakdown cover or specialised policies might offer you protection. Review your insurance policy or speak with your insurer to find out more about your coverage.

Gearbox repair costs vary a lot, depending on the issue and car type. Minor repairs can cost you a few hundred pounds. Major repairs or replacements can potentially cost you more than £1,000. Labour rates and party prices also influence the total cost that you may have to pay. It’s a good idea to get more than one quote for a good estimate.

For the best quality repairs, look for certified mechanics with helpful reviews. Specialists can provide you accurate diagnoses and reliable repairs, keeping your car running as it should.
