This is a problem I had the begin of March more of a " FYI " my Big Horn 2500 kept not wanting to shift out of park . The column shifter would not budge one day I blocked the main gate at my job 5 min no one was happy with that. Took it to the dealer they said a syncro was needed come back in 2 days. It was so bad by then didn't think I would get there. At the dealer I had 2 cars blocked in it locked up completely. I had asked it there was a procedure to get it out of park the dealer had said no , But yesterday I found something in the manual that tells you how to do an EMERGENCY out of park. This was for column & consul shifters listed under "emergency procedures" Hope this helps someone else out.
