See below it uses Dextron ATX fluid

Conventional transfer cases require SAE 80W or SAE 80W-90 GL-5 gear lubricant.
Full time systems use SAE 10W-30 or 10W-40 engine oil.
1981
Conventional transfer cases require DEXRON®II transmission fluid.
1982-85
All transfer cases require DEXRON®II transmission fluid.
1986-87
All transfer cases except the K30/35 series require DEXRON®II transmission fluid.
