摘要： The present invention provides inspection of a transmission with higher precision and in a shorter period of time. Before a finished A/T is inspected, a V/B ASSY and an ECU are inspected together by a V/B tester in a subsidiary line. A solenoid current command value (a characteristic value inherent in the A/T) for a linear solenoid of the V/B ASSY is corrected and written into the ECU through CAN communication. Spring load of a return spring SP and stroke of the piston of a hydraulic servo for a frictional engagement element are measured. Actually measured values or corrected values of the spring load and the stroke are stored. In the final inspection of the A/T a finished-product tester reads the stored characteristic values and transmits them to the ECU integrated with the A/T through CAN communication. The characteristic values are then written into the ECU. The finished-product tester inspects the finished A/T product, using the characteristic values thus written into the ECU.

摘要： In a hydraulic control device, when a solenoid pressure from a linear solenoid valve is not supplied to a brake, which is normally not engaged at the same time as a brake, not to engage the brake, a switching valve is supplied with a line pressure as a signal pressure for establishing a blocked/discharge state in which supply of the solenoid pressure to the brake is blocked and a hydraulic pressure can be discharged from the brake. When the solenoid pressure is supplied to the brake to engage the brake, the switching valve is supplied with a modulator pressure, which is lower than the line pressure, as a signal pressure for establishing a communicated state in which the solenoid pressure can be supplied to the brake.

摘要： To prevent the neutral state from being formed in a change gear apparatus and allow the obtaining of an intended gear change appropriately during a servo malfunction. Hydraulic servos engage and disengage a plurality of friction engagement elements; a hydraulic pressure supply system supplies the hydraulic servo of a predetermined friction engagement element with hydraulic pressure; and an auxiliary hydraulic pressure supply systems supplies a predetermined hydraulic servo with another hydraulic pressure, in the case where the hydraulic pressure supply system is placed in a first unsupplied state where the hydraulic pressure supply system cannot supply the hydraulic servo of the predetermined friction engagement element with hydraulic pressure. The auxiliary hydraulic pressure supply system does not supply the predetermined hydraulic servo with the other hydraulic pressure, in the case that the hydraulic pressure supply system is placed in a second unsupplied state where the hydraulic pressure supply system does not supply the hydraulic servo of the predetermined friction engagement element with hydraulic pressure.

摘要： A failsafe hydraulic circuit designed to avoid simultaneous engagement of two friction engagement elements (e.g., clutches, brakes, etc.) incorporated in a speed change apparatus of a motor vehicle or the like. If a first failsafe valve is in the open position state and a first engaging pressure is supplied to a first hydraulic servo via the first failsafe valve, the first engaging pressure is also input to a first oil pressure switch via a second failsafe valve being in the closed position state. Therefore, using the first oil pressure switch, it can be detected that the first engaging pressure is supplied to the first hydraulic servo. Furthermore, if the first engaging pressure is, for example, greater than the set pressure of the first oil pressure switch, this situation can also be detected. Such detections provide confirmation of normal operation of the first failsafe valve and the second failsafe valve.
