Swapped computer? Did you have it programmed? I hope it was not used as it will never work.

If you have the old one, put it back. There are many checked to be done before going there. From your description. It may be an internal failure. You need a scan tool to verify that it can shift. It can be made to shift through a scan tool to eliminate internal issues.
