A transmission driving mechanism of a transmission in an internal combustion engine is provided in which where a separate transmission driving mechanism for manual operation is not required in addition to an automatic transmission driving mechanism, whereby the number of parts is reduced, the structure is simple, no maintenance is required and the cost is reduced The transmission transmits the rotation of a crankshaft to an output shaft at a modified speed, and includes a transmission driving mechanism which rotates a shift spindle using a shift actuator in order to automatically shift gears within the transmission and change the outputted speed of the engine. One end of the shift spindle extends through an engine case cover, and protrudes outside, and a turning tool is fitted onto a fitting portion formed at the protruding end of the shift spindle, whereby manual shifting of the transmission gears can also be achieved.
