An electronic transmission shifter interlock system in which an electronic module (36) is mounted directly on a shift lever for pivotal movement therewith. The module (36) contains two electromagnetic devices which operate on the spring-biased, shift lever core rod (24) to control the PARK lock release so as to inhibit and/or enable operation of the shift lever according to the status of the ignition lock and the position of the brake pedal. The interlock module (36) is electrically coupled with the ignition lock to prevent the ignition key from being removed while the shift lever is other than the PARK position.

Why it's free to use
- Filed July 24, 1995 and granted May 13, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 24, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 24, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
