There is a 4K RPM limitation when in Park; maybe you cut a wire or accidentally disconnected a plug or did something that is fooling the ECU into thinking that you are still in Park?
Maybe retrace your steps and look for open circuits.

Or maybe something upset the ECU. You could try resetting the ECU; you might get lucky.
