ABSTRACT:
A control system for a shift-by-wire automatic transmission, comprises: a first range changing valve for having an input port switched to communicate with a first output port and a second output port; a second range changing valve for causing the first input port connected with the first output port to communicate with two range ports selectively and for causing a second input port connected with the second output port to communicate with at least another of the range ports selectively; and a drive mechanism for switching and operating the first and second range changing valves. Further comprised are: a fail detector for detecting a failure that either of the first range changing valve and the second range changing valve fails to be switched; and a fail controller for outputting an instruction signal to the drive mechanism to change the range by actuating the switchable one of the range changing valves if the fail detector detects the failure.
