Whoa, WHOA on the auto transmission fluid in the transfer case!!!!!!!!!
The transfer case uses GEAR OIL NOT ATF!!!!
I have always used 80/90weight Lucas gear oil in both front and rear diffs, and in the transfer case. To make the transfer case job alot easier get yourself a fluid transfer pump from your local auto parts shop( they are anywhere from $10-$15) as it is impossible to get a bottle of GEAR oil to the filler hole without it. Only use ATF in obviously an auto trans. and the power steering system!
