The gearbox in your car is an essential mechanical element, when you shift gears, your car’s gearbox transfers engine power to the wheels, allowing you to move forward.

Our professionally trained technicians are on hand to help diagnose any faults with your vehicles transmission system, they understand the difficulties that might arise, as well as the possible remedies that will get your car back on the road.

Transmission fluid that is low or contaminated.

Both manual and automatic transmission vehicles require specialised fluid to keep all the essential mechanical parts moving and assist your gear change mechanism to remain lubricated. That said, transmission fluid does not last indefinitely, it can become low or unclean over time and because of leaks or contamination can become harmful. Both these concerns can prohibit the gears from obtaining as much lubrication as they require, resulting in grinding, overheating, and slippage. Continuing to drive with low or contaminated transmission fluid can lead to total vehicle failure over time.

What is the solution? It’s as easy as applying the proper amount of clean, debris-free transmission fluid to your car. Regular fluid level checks will also allow low levels, pollution, and leaks to be detected early and fixed properly. It’s a good idea to have your vehicles transmission fluid checked regularly and therefore it’s important to stick to your vehicles service plan recommendations. However, the frequency with which the transmission fluid is replaced varies from vehicle to vehicle. Some vehicles and vans only need their transmission fluid replaced every 30,000 miles, while others require it every 100,000 miles.

A worn clutch or gear synchroniser in manual transmission.

The clutch and gear synchronisers are two of the many components that make up a manual gearbox. Failure of one or both of these components can result in serious transmission issues, including total transmission failure. Both components can wear down over time, and mechanical faults can be caused by hydraulic fluid leaks or even human error if the driver changes gears repeatedly without releasing the clutch.

What is the solution? Your clutch or gear synchroniser may need to be changed depending on the extent of the wear and tear to your vehicle’s gearbox. It’s also a good idea to address some of the underlying concerns, such as correcting leaks and modifying driving behaviour.

If the colour or condition of your vehicle’s transmission fluid has changed, the fluid levels are low, you see signs of a leak, your transmission is sliding, or your transmission is overheating, it’s time to contact our expert team for assistance. Make an appointment as soon as possible so you can get back on the road safely and with peace of mind.
