The for-sure answer is to buy new parts and install.  If you've got
more time than money, try cleaning up the existing
one.  Repositioning it slightly may help, there's some slack in the
mounting holes for the purpose IIRC.  The four screws holding the
shifter cover to the floor are hidden under carpet, a nuisance to
peel back.  While you're in there is a good time to replace the two
little light bulbs.  You can leave the cover off or loosely fitted
until you're happy with the switch; the handle is easy to mount or
un-mount with one setscrew.

Yrs,
