you dont put regular trans gear oil in a aluminum transfer case, all transfer cases that are made of aluminum and used in an american built truck are chain driven.. . chain driven transfer case you want to use the latest Dexron fluid out.. . if it had no lubricating properties, and automatic transmission could never survive, let alone the fact that it actually is a detergent oil.

if it is an alumunum case it will be standed tranny fluid . but i as a mechanic for 6 years recommend change it over to 30w nondetergnet oil because tranny fluid has no real lubricating propertys

See if your owner's manual lists the fluid type under "capacities". It's probably transmission type fluid like Dexron III if it looks pink, but that's just a guess.
