The terms "transmission" and "gearbox" are often used interchangeably, but they refer to different aspects of the system:

• Transmission: This refers to the entire system that transmits power from the engine to the wheels. It includes the gearbox, clutch (in manual vehicles), torque converter (in automatic vehicles), and other components that control speed and torque.

• Gearbox: The gearbox is a component of the transmission system that houses the gears responsible for adjusting the engine's power output to the wheels. The gearbox allows you (or the vehicle, in automatic transmissions) to shift between gears for efficient driving.

Common signs of transmission issues include:

• Difficulty shifting gears or delayed gear changes.

• Grinding or shaking during gear changes.

• Slipping gears, where the vehicle shifts out of gear unexpectedly.

• Leaking transmission fluid, usually red or brown in colour.

• Burning smell, which may indicate overheating transmission fluid.

• Unusual noises, such as humming, whining, or clunking when shifting gears.

• Check engine light that may be triggered by transmission issues.

Driving with a faulty transmission is not safe and can lead to more severe damage, such as complete transmission failure. If you experience any transmission issues, it’s important to get your vehicle inspected and repaired as soon as possible to prevent further damage and avoid costly repairs.

It’s recommended to service your transmission every 30,000 to 60,000 miles, depending on your vehicle’s make and model. Regular transmission fluid changes and checks are essential for maintaining optimal performance and preventing problems. Refer to your vehicle’s manufacturer guidelines for the specific service interval.

At QCD Autocentre Brackley, our transmission repair service includes:

• A complete inspection of the transmission system.

• Diagnostic testing to identify specific issues.

• Transmission fluid check and replacement if necessary.

• Repair or replacement of components, such as gears, clutch (for manual vehicles), or torque converter (for automatic vehicles).

• In severe cases, a transmission rebuild may be required, which involves disassembling, repairing, and reassembling the transmission.

A transmission rebuild is an extensive repair that involves completely disassembling the transmission, inspecting all components for wear or damage, and replacing faulty parts such as gears, bearings, seals, and gaskets. After the rebuild, the transmission is reassembled and tested to ensure it operates like new. This is a more cost-effective option compared to a complete transmission replacement.

The cost of transmission repair varies depending on the extent of the damage, the type of transmission (manual or automatic), and whether parts need to be repaired or replaced. At QCD Autocentre Brackley, we provide transparent pricing and will give you an upfront quote before any work begins.

The time required for transmission repair depends on the complexity of the problem. Minor repairs, such as replacing fluid or worn components, can be completed in a few hours. However, more extensive repairs or a transmission rebuild may take a few days. Our technicians will provide an estimated timeframe once the vehicle has been inspected.

Yes, regular maintenance is key to preventing transmission problems. This includes checking and replacing transmission fluid at recommended intervals, ensuring the cooling system is working properly (to prevent the transmission from overheating), and avoiding aggressive driving habits that can put excess strain on the transmission.
