The hazard

VEHICLES EQUIPPED WITH C-6 AUTOMATIC TRANSMISSIONS. SOME AUTOMATIC TRANSMISSIONS HAVE PARK ACTUATION CAM SUPPORT PLATES THAT MAY BREAK DUE TO IMPROPER HEAT TREATMENT. FRAGMENTS FROM THE BROKEN PLATE CAN PREVENT THE PARKING PAWL FROM ENGAGING WHEN THE SELECTOR LEVER IS PLACED IN THE PARK (P) POSITION OR MAY PREVENT THE PARK GEAR FROM DISENGAGING. THIS DEFECT MAY ALLOW A PARKED VEHICLE TO ROLL FREE IF THE MANUAL PARKING BRAKE HAS NOT BEEN ENGAGED.
