All viscosities of Max-Gear are formulated with hypoid friction modifiers necessary for use in clutch or cone type differentials. No additional additives are necessary.

Royal Purple Gear Oil

You don't want 75W 90 in the transmission. It calls for mercron dextron auto transmission fluid. Use Royal Purple's auto transmission fluid.
