Abstract
A switch is shown mounted inside the housing of an automatic transmission of a motor vehicle with a sliding movable electrical contact coupled to the manual valve of the transmission to provide an indication of the position of the manual gear selector. An electrical resistive network is interconnected with stationary contact segments to provide electronic signals to a powertrain electronic controller of the automobile corresponding to the linear position of the manual valve. Pressure switches are coupled to selected hydraulic circuits and electrically interconnected to the resistive network.
