A device comprises a transmission lever (1), a shift position sensor (2), a rotation sensor (3) to measure the rotation speed of a power shaft (9), an inclination gauge (4) to detect the slope of a road surface, a pay-load meter (5) to detect the load of the car, an automatic transmission control device (6), a solenoid valve (7), an engine, a torque converter and a transmission device (8). An optimum speed stage for starting a car is selected by the control device (6) according to the load of the car and the slope of the road surface, i.e the lowest gear is selected for a large load whereas a higher gear is selected for a small load. |
