Hello,
some people recomended to use in transferbox on MT 75 4x4 gearbox a ATF fluid, for better cooling viscous unit and to prevent throw out through trans box breather.
But some people recomended to use in transferbox the same oil like on gearbox.

I decide to use on gearbox an Mobil 1 SHC LS 75W-90, but what oil/fluid You recomended to use in transferbox?

I have freshly rebuild box, with Quaife big tooth gearset, new bearings, new transferbox chain and uprated viscous unit 60Nm.

many thanks for info
