PROBLEM TO BE SOLVED: To reduce cost and weight about an electric wire and mitigate an adverse effect of high current on equipment by shortening the electric wire for high current to an actuator without causing a new cost increase, in a control circuit structure for a mechanical automatic transmission. SOLUTION: The control circuit structure for a mechanical automatic transmission comprises a gearshift unit 31, a power source unit 70, a gearshift driver circuit 33 and a control unit 41. As operationally controlled by the control unit 41, the gearshift driver circuit 33 operatively supplies electric power from the power source unit 70 to the gearshift unit 31 via a power supply line 71 to effect a shifting operation of a mechanical automatic transmission 3 connected to an engine 1. The gearshift driver circuit 33 is arranged nearer to the gearshift unit 31 than to the control unit 41, so that the thick power supply line 71 can be shortened accordingly. COPYRIGHT: (C)2003,JPO
