A common problem when doing the oil change is the removal of the original plastic pan filter this can be made difficult by the cross member being in the way.
The solution, once the pan has been unbolted is to break off the plastic pickup pipe and remove the complete assembly.
Once removed fit the replacement filter and metal sump pan assembly.
This will make future oil changes much easier and also cutting the cost as only the filter will be required and not the whole plastic pan.
Degradation in oil can lead to judder, noise and a deterioration in gear change quality. ZF recommend oil and filter changes after 50,000 to 75,000 miles on all 5, 6 & 8 speed automatic gearboxes to ensure optimum performance.
This is an easy change filter conversion kit for all vehicles using the ZF 6HP26 automatic transmission - Discovery 3, Discovery 4, Range Rover Sport and Range Rover L322 models.
From the factory a fluid and filter change on this transmission is a very lengthy process.
The sump and filter are normally one piece and fitting involves jacking the engine up and unbolting the mounts, plus the removal of the exhaust. The fitting of this kit is far easier.
Once the fluid has been drained from the transmission simply remove the bolts from the old unit.
Cut the old plastic sumps filter tube with a hacksaw.
Slide the old sump out and remove the other end of the sawn off filter tube.
The new separate filter can then be fitted and the new sump pan slides into place and is bolted up with the new gasket supplied.
Once secure the transmission can be filled as per manufacturer’s instructions.
The new sump pan also has the added benefit that it is manufactured in durable steel rather than the plastic of the original item.
