so i got my tranny rebuilt and am putting it back in. the tranny is all in however i forgot to put the transfer case in between the cross member and the motor before i put the tranny in. i dont think i will be abled to get it in the way it is. unless i am wrong. how can i get the transfer case in as easy as possible?

 

try unbolting the front ( both should be out already) and rear motor mount, so just the side trans mount and engine mount by the cam gears are bolted up, or loosen them up a little to make it a little easier to move the motor...
use a pry-bar of some sort and try to rock the whole engine/trans assembly forward and squeeze the tcase in there. It can be done, I just did the same thing in reverse order last weekend, but it is a little tricky to find the right angle. Just be real careful not to crush/dent/break anything when you pry the motor forward, and mind the seals on the transfer case, you DO NOT want to damage those either...
