While I would still pull engine and trans as a unit, the other alternative would be pull the drive shaft, undue the shift linkage and emergency brake, support the transmission and drop the rear cross member, undo the 4 bolts holding the transmission to the bellhousing and remove the transmission. The rear of the engine will also need to be supported as the transmission is pulled to prevent the engine tilting back and breaking the motor mounts.

As supercuda says, "... it is much easier to treat the engine and trans as a complete unit. It is so much easier to mate the two outside the confines of the car than inside it's envelope...."
