Replacing the Gearbox Oil Filter Sump the Fast Way on a Discovery 3, 4 and Range Rover Sport With the Britpart Upgrade

Duration: 8:53

The Skill Shack with Practical Classics team plus colleagues from Land Rover Owner International magazine, visit the Britpart workshop to demonstrate how to use a Britpart oil filter sump to replace gearbox oil on your Land Rover Discovery 3, Discovery 4 and Range Rover Sport.

Britpart supplies a whole kit including the correct quantity and type of oil depending on the speed of your gearbox, a metal sump, the filter and bolts. In this video, Martin explains the tell-tale signs that you may have issues with the gearbox, which may include a slowing down of the change through the gearbox, a bit of slippage when accelerating hard and juddering at low speed.

In this video, Martin from Land Rover Owner International magazine explains how to remove the standard plastic sump tray from underneath the vehicle. Fuzz Townsend shares his top video tip on why and how to clean out all the threaded holes with a tap, before fitting the new sump. The team then show how to fit the new gearbox filter sump and explain how to re-fill with fresh transmission fluid.
