Fresh transmission oil and a dry gearbox casing protect an expensive component. MTS Garage Services handles both for cars and vans around Hayes, with the findings explained before work goes ahead.
Plenty of drivers change their engine oil on time and never think about the gearbox, because it seems to look after itself. In reality the oil inside it works hard, lubricating gears and bearings, carrying away heat and, in automatics, helping with gear changes.
Over time that oil breaks down and collects fine metal particles. For gearbox leak repairs Hayes drivers can come to us. We deal with cars and vans from Hayes, Southall, Uxbridge, Hounslow and West Drayton, and a quick check of the gearbox oil level and condition often tells us more than people expect.

Gearboxes usually give warnings before they fail. The signs below are worth acting on:
Some manufacturers describe their gearbox oil as lifetime fill, which in practice means a fixed period rather than the whole life of the gearbox. Others set a clear interval. The right approach depends on the type of gearbox, the oil it uses and the way you drive. Towing, heavy loads and plenty of stop-start traffic are harder on it. We look up the correct specification for your vehicle, because the wrong fluid can do real harm, and automatics and twin-clutch units are particularly fussy.
Gearbox leaks most often come from shaft oil seals, the sump or pan gasket, a breather, a cooler pipe or the casing joint. We clean the area, look for the source rather than just the lowest wet spot, and check the oil level. A small weep from a seal can be dealt with in a fairly contained way, while a leak that needs the gearbox removed is bigger. We explain which situation you have and what drives the work before you decide. Driving with a low oil level risks serious damage, so do not leave it.
Call us or get in touch with the make, model, engine and registration, whether the car is manual or automatic, and what you have noticed. If you can see a puddle or marks on your drive, tell us where. We will inspect, explain our findings and give you a clear estimate before any work begins.

It varies a great deal between makes, models and gearbox types. Some have a set interval, some claim lifetime fill. We check the manufacturer guidance and the condition of the oil, then recommend what makes sense for how you use the vehicle.
It can be if it is ignored. A slow weep may look minor, but oil level drops over time and low oil damages gears and bearings. It is better to have the source found early, when the repair is usually smaller.
No. Manual, automatic and twin-clutch gearboxes each need a specific fluid, and using the wrong one can cause poor shifting or damage. We use the specification set for your vehicle.
Sometimes it quietens things, particularly if the oil is very old or low. But if parts are already worn, new oil will not undo that. We will check and tell you honestly what to expect.
