Gear oil for the tranny, ATF for the t-case.

Actually, the factory specifies 75W-80, but just about anything close will work fine. There aren't any tight tolerances in a transmission, unlike a crankcase.

Use a GL-4, NOT GL-5 (hypoid), gear oil. Transmissions are not the same as differentials, due to the synchronizers.
