1. A method of controlling a shift-by-wire transmission, the method comprising:
monitoring a setting of a shift assembly that sets a select gear from gearing of the transmission; activating a motor to adjust the setting of the shift assembly when the monitoring of the shift assembly indicates that the then current setting of the shift assembly is outside of a course window of a desired gear, the course adjustment window centered about a nominal target position for the desired gear while being within an acceptable range of the select gear; and shutting off the motor when the monitoring of the setting of the shift assembly indicates the setting is within a fine adjustment window of the desired gear, the fine adjustment window also centered about the nominal target position for the desired gear, the fine adjustment window being narrower than the course adjustment window. |
