Frequently asked questions

What does the gearbox breather do?

The gearbox breather vents internal pressure from the gearbox or transfer case casing. Heat and gear movement build pressure inside, and the breather lets it escape so oil isn't forced past the seals. It's fitted to Defender, Discovery 1 and 2, and Range Rover Classic transmissions.

What happens if the gearbox breather blocks?

A blocked gearbox breather traps pressure in the casing, which then pushes oil out past the shaft and casing seals, causing leaks. Breathers clog with dirt and oil mist over time. Clearing or renewing the breather is a common fix for unexplained gearbox or transfer case oil leaks.

Which vehicles does this gearbox breather fit?

This breather fits the Land Rover Defender (1987-2006), Discovery 1 (from VIN FA393361), Discovery 2 and Range Rover Classic (1986-1994), on both gearbox and transfer case. It suits manual and automatic transmissions. Check the breather location on your casing matches before ordering.
