ive got a borg warner 13-56 transfer case manual shift with a slipyoke rear out put.. truck is an 89 f250 with a 302 and five speed...i blew my old tcase one up and this one is from a junker..but i went to a car quest and asked them what kind of oil and they told me 4 quarts of transmission oil...well so i was filling it up to the fill hole and it only took 2 quarts...now i think they may have mistaken what i said and gave me the oil for the tranny insted...because i think there should be more of like a gear lube in there...input on this would be great! truck will not be driven till im sure about the oil.
i called an old friend of mine and he said older years used gear oil, and mine uses tranny oil..but he said i have to fill it to the hole..then drive it back and forth a little to fill the case up..then keep repeating till its full he said..it makes sense..ill give it a try

According to my Haynes for 1980 thru 1996 Ford Pickups and Bronco:
Transfer case lubricant.............Mercon (Ford Part no. XT-2-QDX or DDX)
Capacities:
Transfer case (U.S. pints unless specified)
Borg Warner 13-56 manual and electronic shift:.........2 U.S. Quarts.
transfer cases are basically transmissions themselves. and like people said, just drive it around and shift it through the 2H to 4L gears and then check level and fill accordingly
