If you do not have them already enough extensions to get about 3ft or so on the end of your ratchet will come in pretty handy for the upper bellhousing bolts, speaking from 4cyl experience only. Also without a trans jack i had pretty good luck leaving the transfer case attached to the crossmenber and just unbolting the 4 bolts that attach the crossmember to the frame. This gave me a little more control over as it was perched on my floor jack.
