Abstract: A manual transmission shifter, which comprises a ball mounting a shift lever, a lateral shift control arm, and a depending shift control member, is mounted in a plastic shifter housing having a plastic closure plate. The housing has a plurality of spaced integral resilient spring fingers contoured to form a socket for receiving the ball. The fingers are interconnected at their upper ends to define an upper opening for the shift lever. The spring fingers define an opening smaller than the ball diameter at their bottom free ends and flex to receive the ball and contract to snugly embrace the ball. The shift control arm projects through a side slot in the housing to enable up-and-down vertical movement of the control arm from a centered neutral position. An integral spring finger biases the control arm to the neutral position. The closure plate has an annular surface which embraces the bottom ends of the spring fingers to define the size of the socket.

Abstract: A throttle valve diagnostic apparatus monitors the integrity of a throttle valve position sensor in an internal combustion engine using an engine parameter indirectly related to the value position. If the absolute pressure of the air in the intake manifold associated with the throttle valve is less than a predetermined pressure for a predetermined amount of time while the position sensor indicates a valve position greater than a predetermined position, the valve position sensor is assumed to be faulty.
