ABSTRACT:
A shift control system for a vehicle transmission with multiple gear trains and a main shaft connected to an engine crankshaft through a clutch. The shift control system allowing shifting without disengaging the clutch. In conducting a shifting operation through a roller synchro mechanism associated with a gear train, the number of revolutions per minute of the engine crankshaft is promptly decreased through at least one of an ignition control device and a fuel supply control means to synchronize the number of revolutions per minute of a main shaft and a counter shaft of the transmission when the number of revolutions per minute of the main shaft is larger than the number of revolutions per minute for synchronizing with the counter shaft and the number of revolutions per minute of the engine crankshaft is increased to synchronize the number of revolutions per minute of the main shaft and the counter shaft when the number of revolutions per minute of the main shaft is less than the number of revolutions per minute for synchronizing with the counter shaft. This enables a prompt shifting.
