Abstract
An automatic gear change device includes a first actuator operation control circuit for controlling the operation of a first actuator, a second actuator operation control circuit for controlling the operation of a second actuator, and a main control circuit for controlling the operation of the first and second actuator operation control circuits. The device further includes a communication line interconnecting the first and second actuator operation control circuits to thereby enable data transmission/reception between each operation control circuit and the main control circuit through the other actuator operation control circuit and the communication line.
