Oh, meant to ask - the manual says to use ATF (!) in the gearbox, and EP85/90 in the diffs and xfer box. Is this still what's recommened, or have there been any factory or local updates on anything better to suit the conditions here?

Also, while on the subject, what's a good coolant (I'm presuming coolant rather than antifreeze for the temperatures here?) to use, as I might as well flush the cooling system out while I'm at it.
