Hi
I would use a 75w-90

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.
Cheers
