I think all the shift selection, as far as the pcm is concerned is done externally as far as starting in gear. I think there is something called shift lock and it is outside the trans. Did you make sure there were no bent pins on the cable that plugs into the trans? sounds more like it is something wrong with the BCM. Most of the devices like motors and solenoids throughout the car will have the voltage at the + of the device, what the PCM does is connects the - (negative) to ground to activate. you don't have adobe acrobat ? if so there should be an adobe "printer" you can print to in your printer folder to create a pdf, also have seen print to a file I am sure, where I suppose if it was in word . also even though the the trans are both the same year and they are both 4T65E's there may be differences inside that their appropriate PCM's have software for.
