from what I recalll, MTF94 is the recommended like said, get it Landrover dealer but it may not be a on shelf stock item any more as they no longer use it in current models (or that's what they said when I last got it from them).
Previously the spec called for ATF, lots of people still use ATF in the R380 mainly because their manual says to do so. Others change to the better MTF94 or similar stuff like difflock evo oil to cure 2nd gear crunch.
