Gearbox Sump & Filter Kit

for Range Rover L322

This is an easy change filter conversion kit for all Range Rover L322 models using the ZF 6HP26 automatic transmission.

When we say "easy" it means you dont need to lift the engine / gearbox. As you will see in the below videos the original sump(plastic) and filter are one assembly and its impossible to remove the sump/filer without lifting the gearbox to clear the chassis cross member. This conversion kit does away with the plastic sump and replaces it a metal sump and separate filter so it is possible to change the filter without lifting the engine and gearbox.

If your gearbox has the ribbed plastic sump it most likely that your car still has its original filter !

Degradation in gearbox oil can lead to judder, noise and the gearbox seems hesitant to change gear.

We are often asked "when should I change the gearbox filter and oil ? " and generally if your gear change is smooth with no thud or hesitation then leave it alone ! Our project car had 200K miles on the original oil / gearbox before we decided to do this chnage. After the change the gear change was smoother and the fuel efficiency improved from 23MPG to 26MPG ( 10% improvement )

See our fitting videos which show the complete removal and refit process on our Discovery 4 (which uses the same gearbox / chassis as the sport ).

This kit includes:

  • Steel sump pan with new sump plug
  • Sump gasket
  • Filter
  • Bolts and washers
  • Fitting Instructions

These are not genuine Land Rover parts.
