Hydraulic automatic transmission control apparatus

A hydraulic control device for an automatic transmission includes: a first check valve (61) having a first input terminal (61a), which (66) is connected to a drain terminal connected, a first movable member (61p) which can be switched to a connection of the first input terminal (61a) to the first discharge port (61b) and for allowing the connection between the first input terminal (61a) and the first discharge port (61b) to interrupt, and a first urging means (61s) for urging the first movable member (61p ), such that the connection between the first input terminal (61a) and the first discharge port (61b) is interrupted; a fail-safe valve (51) is switched to a failure position in the event of a malfunction; and a second check valve (62) having a second input terminal (62a) connected to a forward output port (51d) is connected, and an output port (62b) communicating with the drain port (66) and the first input terminal (61a) in conjunction , The second check valve (62) enables connection of the second input terminal (62a) to the output terminal (62b) at an oil pressure which is lower (smaller) than a predetermined oil pressure (PD). The first movable member (61p) is (is) urged (biased) so as to interrupt the connection between the first input terminal (61a) and the first discharge port (61b) in the case of malfunction.
