After unhooking the battery and removing the engine, remove first the fill plug then the drain plug and drain the oil into a container for recycling. (Take the fill plug out first to be sure you can; draining the transmission if you can't put new oil in it is a Big, Big Problem.) Next, jack up the back of the car and put it on jackstands. Then remove both CV axles (don't try just unhooking the axles from the transmission end, get 'em completely out of there - and this is a great time to repack them while you're here), the backup light wires, the shift linkage and clutch cable.
Next, put a transmission jack under the transmission. Undo all the bolts holding it in, and lower the transmission away from the car.
