I am in the process of doing a transmission oil and filter change on a Range Rover Sport 2.7 .
I have an oil recommend as an equivalent which is Liqui Moly ATF 1800.A$22.50 litre.
I am using a modified steel pan with separate filter so I don't have to jack up engine. Just cut off the filter tube and slide out original sump.
Also I will change the sleeve plug.
