Automatic Transmission Shift Lock Control Actuator Replacement: Notes

WARNING: This page is about a different car, the 2009 GMC Envoy and 2009 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: After assembling the shift lock actuator, turn the ignition forward but do not start (auxiliary position) and attempt to pull the lever from PARK with and without the brake pedal depressed to verify there is no gear access without the brake pedal depressed.

NOTE: Ensure the key cannot be removed from the ignition unless both the shifter is in PARK and the shift knob button has been depressed.
