Hi

You need a 75w-90 for the gearbox.

If you want to go for the best, the Millers CRX 75w-90 NT, Gulf Competition, Motul Gear 300, Red Line MT90 and Millers TRX are ideal for the gearbox. The Castrol Universal/Universal Plus/Syntrans Multivehicle, Motul Motylgear and Fuchs Gear Syn are all decent alternatives.

You need an ATF for the transfer box and I would go for either the Amsoil ATF, Motul Multi ATF, Fuchs ATF4400, Gulf Multi Vehicle ATF, Castrol ATF Multi Vehicle or Millers Millermatic ATF SPIII.
