Yea, the only thing holding the transfer case to the transmission is six-or-so studs (threaded into the transfer case), and the nuts that are on the studs. (Take the nuts off, and the transfer case slides right off the transmission. The studs act as guide pins.)
The transmission output shaft is male, and the input for the transfer case is female.
I don't quite understand what you mean when you say, "in the transfer case that won't allow me to slide it back far enough, due to my not removing the output shaft prior to trying to pull it off."
The only thing you should have to remove to get the case out is: remove driveshafts, disconnect the shift linkage, disconnect the breather hose, disconnect the vacuum hose or electrical wires and remove those 6 nuts.
Now, I did have an issue: my transfer case was basically corroded to the transmission. I had to remove the transmission and transfer case as one unit, and then use a wood block and sledgehammer to remove it (yea, it was really stuck on)
DO NOT DISASSEMBLE THE TRANSFER CASE TO SEPARATE IT FROM THE TRANSMISSION! IT WILL NOT WORK!
