If its a newer automatic it should be fairly easy. Just unplug all the electronics, the auto shifter linkage, driveshaft, tranny mount and your good to go. For the engine, its disconect all electronics, motor mounts, and everything else holding it in.
If its a manual, disconnect everything mentioned above except itll be manual shifter lnkage instead.
AND if its 4x4, itll be even harder... disconnect front driveshaft, rear driveshaft, disconnect transfer case, drop transfer case, then do tranny stuff... Am I making sense lol. Im tryin to hit all bases.
Im sure someoen can explain better tho...
