There is no Transfer case oil. Just Transmission oil and that goes in the dipstick tube after the dipstick is removed. if its a standard there is a plug on the side of the tranny underneat fill to plug level
Gear oil...usually 75w90 weight. I would use Royal Purple or any synthetic gear oil. That goes for both differentials and the transfer case.
