Motorcraft MERCON automatic transmission fluid is used in the transfer case
when under the truck looking at the transfer case there is a plug that a 3/8 rive ratchet will fit in to, take it out then you will have to get an evacuator to pull the fluid old fluid out, u will need an air compressor also, if u dont have this equipent,thn your best bet is to go to an oil lube shop and have them do it its not very expensive.
I belive the transmission will take sincromesh fluid found and any gm dealer and your transfer case will take dexatron III fluid.
The transfer case typically takes about 1 to 2 quarts of fluid. It's always best to consult your vehicle's owner's manual for the specific fluid capacity for your transfer case.
