My transfer case needs replaced, low is at the least chewed up gears. 2wd still fine... am looking for used transfer cases, found a np 263 for a good price. I'm hoping that i have to replace nothing but the diff... but I don't know for sure so am asking here. thanks ahead of time.

If I'm not mistaken the np 263 doesn't have clutches in it like the 246 auto trac? I like that idea... would like to know if that's true. Also, would i need to replace the 4wd selector switch for one that i assume doesn't have the Auto button? would it be that simple? or... would i need to replace the control box that's back behind the 4wd switch as well?
