I have a 2010 1500 Laramie, Crew cab, 4wd. Yesterday I got in the truck and it started right up no issues, drove it to my destination parked it and shut it off. Went to move it quickly about 1 minute later got in tried to start it and put it in gear and I may or may not have put it into reverse too quickly as the engine was cranking, not really sure as I wasn't paying too much attention to the sequence of events. Either way, now when i turn the key all the normal lights come on, (along with a check engine light), power to everything seems fine but it won't crank in P, N, or any gear, nothing, Also, and im not sure what this means (if anything) if I put the shifter in any gear other than park I can manually roll the truck forward and backward fairly easily. The shifter cable is working and moving the gear selector arm back and forth. Just wondering where to start? Neutral safety switch? Range sensor? any of 1000 other things?
TIA
John

Edit: All the fuses and relays appear good.
