ABSTRACT:
An automatic transmission system for a vehicle which is so arranged that a medium speed ratio is first achieved and then a low speed ratio is achieved when the speed ratio is to be shifted from a high speed ratio immediately to the low speed ratio, in which, when the vehicle is running in the high speed ratio of the transmission and a selector lever is set to a position instructing a shift to the low speed ratio expecting an engine braking effect (speed reduction feeling), a hydraulic pressure to provide the same speed reduction feeling as obtained from the engine braking effect in the low speed ratio is supplied to the frictional engaging element to achieve the medium speed ratio, during a shift from the high speed ratio to the medium speed ratio.
