Abstract

PURPOSE: To provide a good maneuverable automatic transmission which can obtain stable vehicle speed retainng function and retain the speed while automatically shifting to suitable gear ratio when the running load of the vehicle is varying.
CONSTITUTION: This automatic transmission automatically shifts the gear ratio via a hydraulic actuator 21 upon reception of a position signal from a selector lever 19, a vehicle speed signal from a speed sensor 16, a throttle opening signal from a throttle sensor 18, and a clutch signal from a clutch sensor 28 or the like with a computer 8 for opening or closing a throttle valve by supplying suitable vacuum or atmospheric pressure to a throttle closing unit actuator 29. A vehicle speed button 60 is added to the computer 8 to drive a vehicle speed retaining actuator through a control valve 49 so as to thereby suitably open or close the throttle valve.
