Calibration of an X-Y shifter is, accomplished under the control of a microcomputer (28) which is programmed to perform a calibration routine each time the vehicle is shutdown. The routine causes the shifter's shift finger (10) to be moved into touching contact with the various inner wall surfaces (11F, 11R, 12F, 12R, 13F, 13R, 11X, 13X) of a plurality of shift blocks (11, 12, 13) of the respective transmission shift rails (14a 14b, 14c), from which a calibrated shift rail and neutral position are calculated.

Why it's free to use
- Filed November 12, 1993 and granted February 15, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 12, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 12, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
