Ford F Series, Econoline: Powertrain

The hazard

A SNAP RING WHICH LOCATES THE PARK GEAR ON THE OUTPUT SHAFT OF THE TRANSMISSION MAY FRACTURE AND ALLOW THE PARK GEAR TO SLIDE REARWARD. THIS WOULD MAKE IT IMPOSSIBLE TO ENGAGE THE PARK GEAR AND COULD RESULT IN VEHICLE MOVEMENT EVEN THOUGH THE GEAR SELECTOR IS PLACED IN THE PARK POSITION. CORRECTION: AFFECTED VEHICLES WILL HAVE THE SNAP RING REPLACED WITH AN IMPROVED SNAP RING. IN ADDITION, A REVISED TRANSMISSION EXTENSION HOUSING WILL BE INSTALLED WHICH INCORPORATES A CAST STOP THAT WILL LIMIT PARK GEAR MOVEMENT EVEN IF A SNAP RING SHOULD FRACTURE.
