you might need to swap more than the PCM, i believe the communication protocol between the different control modules is different than the 04 so you most likely need PCM,full wiring harness, FCM, air bag module, abs, and maybe more

i looked into this and it seems to be more trouble than its worth. the person that referred me to it was confused and thought for some reason i wanted to put a manual trans in my truck, but from the other stuff i read it is possible, just a PITA
