ABSTRACT:
A Park inhibition solenoid assembly for preventing the undesirable shifting of a transmission from an out-of-Park mode to a Park mode includes a follower and an armature slidably disposed within a valve body/housing and within a solenoid. The follower is moveable between an out-of-Park position and a Park position and the armature is moveable between an unlocked position and a locked position. The follower and armature include detents for supporting a bearing. The armature and bearing prevent the follower from moving from the out-of-Park position to the Park position when the armature is held in place in the lock position by the solenoid.
