A method and apparatus for controlling a shift-by-wire transmission comprises providing a multi-stable selector 17 which via an indexing mechanism 24 provides a peak and trough force feedback to a driver so as to enable the driver to perceive a transition from one stable position to another. An output from at least one senor 18 is calibrated such that, when the selector 17 is located at any one of the peak force feedback positions, a single from the sensor 18 always results in an electronic controller 20 selecting a drive mode, e.g. reverse or forward, in the transmission. The output from the senor 18 may consist of a range which is divided into a number of bands having upper and lower limits. When the selector 17 is moved from park to reverse, reverse to neutral, neutral to drive and drive to sport the limits are higher than when the selector 17 is moved from sport to drive, drive to neutral, neutral to reverse and reverse to park. |
