ABSTRACT:
An hydraulic control device for an automatic transmission includes a plurality of controlling valves connected to related friction engaging elements. A plurality of solenoid valves are connected to the controlling valves for supplying hydraulic pressure thereto. A checking device determines whether an upshift of the transmission is performed or not. A detector determines a detected value of either a RPM count of an engine of the vehicle or a longitudinal acceleration of the vehicle. A fail-safe device prevents the upshift based on a comparison of the detected value with a predetermined value.
