An electronically controlled transmission in which a single drive motor is used to drive a shift shaft, in which shift shock is reduced during continuous running. The transmission has a shift shaft, an actuator, a gear box and a control portion. The actuator causes the shift shaft to rotate. The gear box includes a gear shift mechanism, a clutch mechanism, and a crank case that houses the gear shift mechanism and the clutch mechanism. The gear shift mechanism is activated in association with rotation of the shift shaft. The clutch mechanism connects and disconnects transmission of power to the gear shift mechanism from the engine in association with rotation of the shift shaft. The control portion controls the actuator based on the temperature of the gear box.
