Before you go that route, I'm certain that HP tuners has the ability to flash the Auto PCMs. You need to grab an 05 Ram PCM, and it should work with all of the JTEC wiring. I'm in the process of gathering the remainder of my parts for my Hemi Swap into my 02 Quad Cab. I'm also going 5spd as well. Try researching modernmuscle.biz. Dave is the owner of the site and has performed many Gen III Hemi swaps into older muscle cars, and trucks as well. There are lots of good sites on the modern hemi, that should be able to help you out. Hit me up in a PM if you need more info. Also there are very knowledgeable members of this forum as well.
