Frequently asked questions
It’s difficult to provide a definitive answer without a proper diagnostic, as the cost of a gearbox repair can vary depending on several factors. The make and model of the car, as well as the type of gearbox, can significantly impact the cost.
If you’re experiencing issues with your gearbox, the best course of action is to contact us and one of our specialist team will be able to provide you with an initial quotation.
There are several factors that can contribute to a gearbox becoming faulty. Some of the most common causes include:
Lack of maintenance: Regular maintenance, including changing the gearbox oil and replacing worn parts, can help prevent damage to the gearbox.
Wear and tear: Over time, the gears and other components of the gearbox can become worn, leading to issues such as grinding or difficulty shifting.
Overheating: Excessive heat can damage the gearbox and cause it to fail. This can be caused by a variety of factors, including driving at high speeds for extended periods or towing heavy loads.
Contamination: Dirt, debris, or other contaminants can get into the gearbox and cause damage to the gears and bearings.
Manufacturer defects: In some cases, the gearbox may have been manufactured with a defect that causes it to fail prematurely.
It’s not recommended to continue driving your car if you’re experiencing problems with the gearbox. While you may be able to drive for a short time, ignoring the issue could result in more severe damage to the gearbox and other components of your vehicle.
Continuing to drive with a faulty gearbox could also turn a simple repair into a more complex and expensive one. In some cases, driving with a damaged gearbox could lead to complete gearbox failure, which could result in extensive damage and costly repairs.
If you’re experiencing issues with your gearbox, it’s important to have it diagnosed and repaired by a professional as soon as possible.
