Pretty common problem..looks like the rubber shifter cable bushing has fallen off...these are just a press fit to the pin on the metal shifter arm,and have no "e" clip on them from the factory to keep it locked in position.Pretty sure you have to buy the whole cable assembly to obtain this bush(GT legend may be able to confirm this).Your suggested solution of fitting a rubber bush and c- clip will work as i have seen this done before to eliminate the slop in the shifter after this bushing has fallen off.
