Abstract
A shift by wire transmission system enables a driver to manually select a next desired gear and the system completes the shift automatically without requiring the driver to operate the clutch. The system includes an electronic transmission control unit that communicates with an electronic engine control unit to control engine speed during a shift in order to synchronize the speed of an engine shaft and the transmission shaft. The driver manually chooses a gear shift by moving a shift lever to thereby produce electrical signals indicative of the desired change in gears. Multiple or skip shifting is possible along with a method of automatically choosing a default gear in the event that the vehicle transmission is placed in neutral while the vehicle is in motion.
