2012 RT SE5 starts OK then shuts down when 1st or R selected - ideas?

Ok so I did something questionable... Bought a 2012 RT SE5 from a shop that took it in on trade. It's across the country at my Daughter's house in Bremerton, WA. I'm an hour west of Boston. It idles fine (now that she replaced the battery) but when she shifts it into gear it shuts down and stays in that gear, either 1st or R. No errors on the dash at all. She has to manually shift it back to neutral with a wrench. Shipping company is picking it up this week to bring it to me. So that gives me a week or two to brainstorm and get a checklist in place. I'm thinking I need to start with the gearbox position sensor and work out from there. Thoughts?
