摘要：
在向C1切换阀80供给主压PL来作为保持压时，或供给调节压Pmod来作为保持压且不供给B1电磁压Pslb1时，C1切换阀80形成能够向离合器C1供给C1电磁压Pslc1的第一供给状态；在向C1切换阀80供给调节压Pmod来作为保持压且供给B1电磁压Pslb1时，C1切换阀80形成能够向离合器C1供给主压PL的第二供给状态；并且在C1电磁压Pslc1的供给异常时，向C1切换阀80供给调节压Pmod来作为保持压。
摘要（英）：

A C1 switching valve (80): forms a first supply state that enables a C1 solenoid pressure (Pslc1) to be supplied to a clutch (C1) when a line pressure (PL) is supplied as a holding pressure, or when a modulator pressure (Pmod) is supplied and a B1 solenoid pressure (Pslb1) is not supplied as a holding pressure; and forms a second supply state that enables the line pressure (PL) to be supplied to the clutch (C1) when the modulator pressure (Pmod) is supplied and the B1 solenoid pressure (Pslb1) is supplied as holding pressures. Furthermore, the modulator pressure (Pmod) is supplied to the C1 switching valve (80) as a holding pressure when there is a supply abnormality in the C1 solenoid pressure (Pslc1).
