ABSTRACT:
A fully automatic transmission system for a vehicle eliminates the use of hydraulic or electromagnetic valves to control speed change, and instead utilizes clutches to change shift and disconnect power transmission, to minimize power consumption during idle shift, and to prevent slipping of the vehicle during climb on an upgrade, respectively, when no power is transmitted to the vehicle wheels, and without the need to brake the vehicle. When the revolving speed of the vehicle engine is slower that that of the transmission shaft, idle rotation of the system's clutch lining connector is automatically prevented.
