I need to use a 2003 Rubicon preferably for a short period of time to test a SKIM module and PCM in. We would remove your PCM, SKIM, ignition cylinder and replace them with the test pieces to see if they are good. Maybe a short test drive around the block to verify that the auto shifts correctly. It may not even start and take less time. We will put your rig back to the condition it arrived in and be responsible for anything untoward that happens. Any Help out there?
