Abstract

A control system for an automatic transmission includes a torque converter which hydraulically transmits rotation of the driving power source to the speed change gear unit, a first friction engagement element, a second friction engagement element, a third friction engagement element, a vehicle stopping detecting mechanism for detecting a vehicle stopped condition when a forward driving range is selected, a vehicle weight detector, and a controller. The controller controls the disengagement of the first and second friction engagement elements and the engagement of the third friction engagement element with an engaging force in response to the vehicle weight when the vehicle stopped condition is detected while the forward driving range is selected.
