An automatic transmission shift control device which prevents shifting from the "Park" position to any other position unless the ignition key is at the "on" position and the brake pedal is fully depressed. A safety feature is incorporated so as to insure against accidental gear shifting. To shift the control from the "Park" position a control button located on the shift handle is manually pressed. The control button mechanically depresses a linkage rod which in turn moves the shift position pin out of its "Park" locking position. However, the linkage rod cannot move downward unless a bushing which has clearance slots for the position pin is rotated by a solenoid, which is acuated only when the ignition is "on" and the brake pedal is pressed. Also, the bushing surface in proximity to the bushing slots is shaped so as to prevent accidental engagement of the positioning pins.
