ABSTRACT:
A gear shift device for a vehicle automatic transmission has a gear shift lever for placing an automatic transmission of an automotive vehicle in any desired gear range. The gear shift device further has an electrically controlled shift lock mechanism for locking the gear shift lever so that the transmission is fixed in a park gear range when a brake pedal is released, and for enabling the gear shift lever to operate when the transmission is in the park gear range, when an ignition key is set and the brake pedal is pressed. A mechanically operated interlock mechanism is provided for enabling the ignition key to be pulled out when shifting of the gear shift lever has placed the transmission in the park gear range.
