ABSTRACT:
A vehicle transmission system has an internal lever for changing transmission gears, a select actuator for moving the internal lever to neutral positions N1, N2, N3 in a first direction, a shift actuator for moving the internal lever to 1st-5th gear positions and a reverse position in a second direction substantially normal to the first direction, and a clutch actuator for actuating a clutch. While any one of the actuators is in operation, the pressure of a fluid discharged from the operating actuator is prevented from acting on the select actuator and/or the shift actuator which is not in operation by applying a fluid pressure to the inoperative select actuator and/or the shift actuator to fix the actuator or actuators in a current position against operation, thereby allowing the transmission gears to be changed accurately and smoothly.
