From what casey told me today, it wont hurt a thing to run the truck without an edge. the service required ding will get annoying, but wont hurt anything. make sure the plug on the side of the tranny is unplugged until you get an edge or have a way to clear codes upon start up. i started clearing my codes today with my 5.9 triple dog, so i plugged my sensor on the tranny back in. Hope that helped!
