I was under my truck a few days ago changing the rearend oil out. I thought that maybe i would drain the transfercase and put some new fluid in it to. There is a drain plug and a fill plug. When I took the drain plug out there was about two gallons of tranny fluid that came out before i put the plug back in. The tranny fluid was low all of a sudden, too. Is the transfercase a seperate system from the tranny. Because if so I've got a bad seal or something. I don't think that there is supposed to be that much fluid in the transfercase. I don't know how long its been like that, but if it is a problem, would it hurt to make a 1300 mile trip. Any information would be helpfull.
