Hello and thank you for your question,

See the transmission specs in the first link,

  • All 4-speed transmissions-SAE 85W/90 gear oil

  • All 5-speed transmissions-MERCON® (Dexron®II) ATF

    And the transfer case in the link below,

    Transfer Case Fluid Type also calls for -MERCON® (Dexron®II) ATF

    The rear Differential calls for 90w gear oil .

One other thing, if you have a limited slip rear diff be sure to add some friction modifier as well .
