Abstract
A control system and method for communicating with a transmission includes a transmission input speed sensor that generates an input speed signal. A transmission output speed sensor generates an output speed signal. A power supply supplies a total current to the transmission input and output speed sensors via a first conductor. A sensor senses the total current supplied to the transmission input and output speed sensors on the first conductor. A calculating module calculates a transmission input speed and a transmission output speed based on the total current.
