American Nightmare

So I got a PA shift kit for my 02 GT and the instructions are awful. It doesn't say how to remove the valve body, and it begins with "Remove 8 check *****, drain back valve, filter, and PR valve train from valve body. Thoroughly clean valve body with solvent. Blow off with compressed air." I'm completely new to this sort of thing, so I have no idea how to do this. If anyone has a detailed explanation of how to install this I would be extremely grateful.
