Abstract
An electronic transmission shift control is provided wherein an input device such as a vehicle control lever is connected to a sensor. The sensor sends out a substantially continuous signal to an electronic control module. The electronic control module controls the current going through a solenoid that, in one application, is controlling the pressure of a valve to engage a clutch in a transmission.
