ABSTRACT:
A speed change control unit of an automatic transmission for automobiles including a hydraulic servo for achieving speed change operations electrically and hydraulically controlled depending upon the operating state of an engine. The flow rate of working oil for the servo having a substantially constant pressure applied thereto and flowing through an orifice is detected so as to control the operating speed of the hydraulic servo in accordance with the flow rate, whereby changes in the characteristics of the hydraulic servo ascribable to the temperature change and quality fluctuation of the working oil of the transmission can be thereby compensated for so as to ensure a smooth speed change operation at all times.
