THE TRANSMISSION SHIFT-CABLE LOCK CLIP CAN BACK OUT OF ITS INSTALLED POSITION RESULTING IN A LOSS OF CABLE ADJUSTMENT. WHEN THE SHIFT LEVER IS PLACED IN THE "PARK" POSITION, THE "PARK" INDICATOR LIGHT MAY NOT ILLUMINATE.
THE VEHICLE CAN MOVE UNINTENTIONALLY IF THE DRIVER DOES NOT NOTICE THAT THE INDICATOR LIGHT IS NOT ON AND DOES NOT APPLY THE PARKING BRAKE.
DEALERS WILL ADJUST THE SHIFT CABLE AND INSTALL A LOCK CLIP.
