Some of these vehicles may be equipped with automatic transmissions that were assembled with improperly manufactured cast iron extension housings. The housings have mislocated cast cam plate stops. A mislocated stop may prevent the transmission from locking in the park position when the gear shift selector lever is placed in the "P" (park) position. If this occurs a driver may rely upon the reading on the gearshift selector lever indicator and may assume that the transmission parking gear is engaged.
