Transfer cases are not like Transmissions they don't have drain pans. They only have drain and fill plugs. Transfer cases do not have filters either.
Similar to any other gear box, there are two drain plugs, one on the bottom, and one on the back half way up the side. Drain from the bottom, and fill from the side, when fluid trickles out of the fill hole it is full.
