Abstract
A rotatable selector mechanism for a motor vehicle transmission has a selector knob rotatable in a housing to select an operating mode of the transmission among a number of selector positions indicated by a label (P, R, N, D, M). The selector mechanism further includes a detent plate which cooperates with a detent pin for maintaining the selector knob in each of positions. The detent plate is connected to position sensors for generating selector signals to a transmission control unit which supplies control signals to an actuator for operate the transmission according to the operating mode selected. The detent plate is also associated to the selector knob and to a drive correction means by means of clutch devices respectively to engage the detent plate to one of the selector knob and the drive correction means. The clutch devices and the drive corrections means are controlled by the transmission control unit to move the detent plate from a selector position selected by the driver to another selector position representative of the operating mode of the transmission by means of the drive correction means without moving the selector knob. The selector knob further includes an illuminat…
