ABSTRACT:
Hydraulic pressure regulated by a first pressure control valve is supplied to an electromagnetic changeover valve. The electromagnetic changeover valve changes over the hydraulic pressure between a low & reverse passage communicating with a low & reverse brake and a high clutch passage communicating with a high clutch, thereby a simultaneous engagement of the low & reverse brake and the high clutch can be avoided and further the simplification of the hydraulic control apparatus of an automatic transmission can be realized.
