Motor and PCM are out of an 05 model 6.0. OS#12606807. I have flashed the car and removed the VATS and got it to where it will fire up and run. He has installed a NV4500 transmission. I need the segment swapped over to a manual transmission. Is there any way I can do this myself or is there really alot to it. I didn't know if I could just change his OS to a manual file or if I had to have somebody do all of this for me.
