With intrument cluster not displaying the correct gear this is due dirty contacts on the inhibitor switch. The switch is located under cover of the transmission gear lever. Take the switch out (2 screws and a plug) and open and clean all contacts in it. My car had the same problem and it wouldn't sometimes shift properly due to the switch.
