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.
Dealer will inspect and, if necessary, replace the transmission extension housing without charge to owner.
Vehicle description: light trucks equipped with c-6 automatic transmission. System: power train; transmission. Consequences of defect: if the parking brake is not engaged and the vehicle isleft unattended while still in gear, it could roll free, causing injury anddamage to persons and property.
