Abstract
A shift range control system for an automatic transmission, comprising: a first range switching mechanism for selecting a shift range mechanically; and a second range switching mechanism for outputting an electric signal, while a predetermined shift range is being selected by the first range switching mechanism, to switch the shift range electrically. Further comprised is a return switch mechanism for releasing the shift range, which is lower by two or more steps than the predetermined shift range selected by the first range switching mechanism, to switch the same to the predetermined shift range. Thus, it is possible to improve the conveniences for switching the shift range of the automatic transmission by the electric operation.
