Abstract
A selector lever includes a housing with front and rear ends and a lever with a shaft pivotally disposed on a cross-shaft. The shaft defines a shaft axis. The lever has a top that is disposed outside of the housing. A movable shaft moves substantially axially along the shaft axis. A pin, having first and second protrusions, is disposed adjacent to a bottom end of the movable shaft. A first detent plate is disposed on a first side of the movable shaft and includes at least a first slot that receives the first protrusion. A second detent plate is disposed on a second side of the moveable shaft and includes at least a second slot therein receiving the second protrusion. A first failure detection slot is associated with the first slot, permitting movement of the first protrusion therein in the absence of the second protrusion.
