I'm in the middle of the same thing right now on my 92 4x4 explorer.
1. Disconnect all wires from the tranny and transfercase, including the speedo cable (your's might be electric?)
2. Remove starter
3. Disconnect front and rear driveshafts from t-case.
4. Remove shifter.
5. Remove exhaust y-pipe (boy was a ***** up here in the salty midwest

)
6. Support transfer case with jack
7. Remove tranny cross member.
8. Slowly lower jack supporting transfercase while watching clearence between the oil pan and front crossmember. You should be able to lower the back of the transfercase about 8".
9. Support engine in it's lowered position.
10. Lowering the back of the transfercase should now have allowed access to the bolts securing the tranny to the engine.
11. Support the transmission.
12. Remove the bolts holding the tranny to the engine. There are eight and they have 13mm heads. I used an impact wrench with about 2' of extension and a u-joint.
13. At this point you should be able to slowly work the tranny/t-case apart from the engine.
14. Once it is free, carefully lower the tranny and tcase and set aside.
I would replace the clutch disc, pressure plate, pilot bearing, throwout bearing, and slave cylinder and at least resurface the flywheel when you are in there.
Now is also a great time to replace the leaky rubber plugs on the top of your tranny with 5/8" metal freeze plugs. Also change the fluid in the t-case and tranny if it hasn't been done recently.
Installation should the reverse of removal, but I haven't gotten there yet.
Hope that helps!
