Gearbox Oil Leak – Causes, Risks & Professional Repairs
A gearbox oil leak should never be ignored. Transmission fluid is essential for lubricating and cooling your gearbox, and even a small leak can lead to major internal damage if left untreated. Whether it’s a worn seal, damaged gasket, or cracked casing, our experienced technicians can quickly locate the source of the leak and carry out high-quality repairs. We work on both manual and automatic gearboxes, ensuring your transmission runs smoothly and reliably for years to come.
Common Signs of a Gearbox Oil Leak:
- Patches of red, brown, or amber fluid under your vehicle
- Difficulty changing gears or rough gear shifts
- Gearbox warning light on the dashboard
- Burning smell caused by overheating transmission fluid
- Unusual gearbox noise or whining
What Causes Gearbox Oil Leaks?
- Worn or damaged output/input shaft seals
- Perished gaskets or O-rings
- Cracks in the gearbox casing
- Loose or damaged drain plugs
- Excessive internal pressure due to blocked breathers
How We Fix Gearbox Oil Leaks:

Why Act Quickly?
Low gearbox oil levels can cause severe internal wear, overheating, and even complete gearbox failure. Repairing a leak early is far cheaper than rebuilding or replacing a damaged transmission.
