Abstract
A control system for an automatic transmission, when hydraulically controlling the speed ratio of a belt type continuously variable transmission that transmits power from an engine to driving wheels by shifting or speed change, limits the shift speed to or below a predetermined value when an accelerator pedal is off and the engine rotational speed is at or below a predetermined speed. As a result, it is possible to avoid a driver from feeling uncomfortable when shifting with the accelerator off.
