Abstract

PURPOSE:To prevent shocks due to speed change even with varying oil viscosity by changing the controlling characteristic in supply control of the actuating oil pressure to No.1 and No.2 friction engagement elements, which serve speed changing, in accordance with the oil temp. CONSTITUTION:A changeover timing adjusting means of a hydraulic control device for an automatic transmission permits a hydraulic control means to perform adjusting action for the period from the changeover timing of engaged condition in No.1 friction engagement element to another changeover timing of engagement condition in No.2 friction engagement element in accordance with the temp. of a working oil sensed by an oil temp. sensing means or a temp. associate therewith. This provides properness according to the oil temp., i.e. viscosity of working oil, in the period from the changeover timing of the engagement condition in No.1 friction engagement element till changeover of engagement condition in No.2 friction engagement element. This can suppress generation of large speed change shock, unintended blowup of the number of engine revolutions, etc.
