Abstract
An electronic transmission shifter interlock system in which an electronic module is mounted directly on a shift lever for pivotal movement therewith. The module contains two electromagnetic devices which operate on the spring-biased, shift lever core rod 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 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.
