As far as a jack, use whatever you can find that is STABLE enough to hold it in place long enough to do it. I used an ATV stand when I did mine(I don't own a tranny jack either).
Disconnect both driveshafts, vacuum modulator, kick-down cable, tranny lines /forums/images/graemlins/dunno.gif(depends on slack)tranny linkage, maybe the tcase shifter arm thru the floor. I think that is all i had to do. Been about a yr since the last time I did it.
