AS A RESULT, FRAGMENTS FROM A BROKEN PLATE CAN BECOME LODGED IN THE TRANSMISSION PARKING PAWL MECHANISM. THIS COULD PREVENT THE TRANSMISSION PARKING PAWL FROM ENGAGING WHEN THE SELECTOR LEVER IS PLACED IN THE "PARK" POSITION, OR PREVENT THE PAWL FROM BEING DISENGAGED FROM THE PARK GEAR.
THE DEALER WILL REPLACE THE PARK ACTUATION CAM SUPPORT PLATES, FREE OF CHARGE, ON ALL AFFECTED VEHICLES.
