A lot of good advice here, one more thing be sure to un hook the wiring to your transmission from under the hood and pull it out with the transmission, and have lots of hands to help with that thing because that is a beasts if you are on your back. And prop the motor up so it does'nt tweak your motor mounts. Good luck.
