The first upshift is performed from the first gear to the second gear if vehicle acceleration is above zero for the second gear, and current engine speed is in the first range of engine speed. The second upshift is performed from the first gear to the third gear if current engine speed is in the second range of engine speed. The first range of engine speed is the range of lower engine speed than the second range of engine speed. The system comprises transmission control unit. The control unit performs control of transmission based on steps of above mentioned method. Vehicle, such as truck or bus, contains above described system.

EFFECT: efficient engine output power usage at gear shifting.
