Abstract
A manually operable shift control mechanism operatively connected with a transmission through an electro-hydraulic control circuit for selectively establishing one of a plurality of speed ratios in the transmission, the control mechanism including a pivoted lever angularly movable between successively arranged positions for establishing one of the speed ratios in the transmission, and a detent device coacting with detent cut-outs on a control plate for releasably maintaining the lever in each of the transmission settings and affording a distinct "feel" to the operator for each transmission setting, as well as an electric circuit board on the control plate operatively interconnected with the transmission control circuit, with the circuit board being provided with a plurality of spaced electric proximity switches that are activated by a magnet means carried by a pivot arm member movable with the lever.
