A shift lever control device for an automotive transmission by which a shift lever can be shifted from a Park position to a Reverse position or vice versa only when the park brake is in opertion and the engine has been started. The control device comprises a shift lever control means having a plunger and an electromagnetic actuation mechanism, an ignition key switch and a park brake switch, in addition to a conventional shift lever device having a shift lever, a position plate, a pin, and so forth. The ignition key switch, the park brake switch, and the electromagnetic mechanism are connected in series between a power supply and ground, so that if the park brake is released or the engine turned off, the electromagnetic mechanism is operated to actuate the plunger to drive the pin of the gear shift level into engagement with a Park position slot. The control device is also intended to prevent the dangerous situation when the shift lever is accidentally set to the park position while the engine is running. |
