摘要： In a hydraulic apparatus for an automatic transmission having a torque converter with a lockup clutch and CVT, there are provided a first control valve for controlling hydraulic pressure supply to the lockup clutch oil chamber, a first electromagnetic solenoid valve for controlling operation of the first control valve, a second control valve for controlling hydraulic pressure supply to the CVT pulleys, a second electromagnetic solenoid valve for controlling operation of the second control valve, a switching valve interposed between the oil chamber and the first control valve. In the apparatus, when detecting that the first control valve or first electromagnetic solenoid valve is failed and the lockup clutch is locked in engaged condition, current supply to the second electromagnetic solenoid valve is stopped so that it operates the switching valve to disengage the lockup clutch, thereby enabling to forcibly release the engagement without manipulation by the operator.
