Abstract: A controller for a vehicle propulsion system that includes a prime mover, a transmission connected to the prime mover to receive input torque on an input shaft and to convert the input torque to an output torque on an output shaft, a transmission input shaft speed sensor, and a transmission output shaft speed sensor. The controller provides a gear ratio value that is based upon a signal indicating an operating condition of the transmission other than a signal from the transmission input shaft speed sensor and the transmission output shaft sensor.
