DISCOVERY 3 AND 4 ZF 6HP26 AUTO GEARBOX METAL SUMP PAN AND FILTER KIT This is an easy change filter conversion kit for all vehicles using the ZF 6HP26 6 speed automatic transmission. 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 .
