    Bulletin No.: 08-07-30-007B

    Date: June 08, 2009

    Subject: EI08045 - Key Cannot Be Removed from Ignition with Gear Selector in Park, Shifter Cannot Be Moved from Park Position (Repair/Reroute Brake Transmission Shift Interlock (BTSI) Solenoid Harness)

    2007-2009 Chevrolet Impala

    Supercede:This bulletin is being revised to end the need for information from the field and provide repair information. Please discard Corporate Bulletin Number 08-07-30-007A (Section 07 - Transmission/Transaxle).


    Some customers may comment on either of the following conditions:

    - The key cannot be removed from the ignition.
    - The transmission gear selector (shifter) cannot be moved out of the PARK position.


    This condition may be caused by an incorrectly routed brake transmission shift interlock (BTSI) solenoid harness which can make it difficult to install. In some instances, the wiring looms are tangled, causing stress on the wires in the connector at the BTSI. If the BTSI harness is routed incorrectly, it may also result in a wire pinching issue.


    DO NOT use force to move the gear selector (shifter). Using force may cause damage to the BTSI.

    Inspection/Routing and Repair of the BTSI Wiring Harness/Connector

    1. Check for wire damage at the BTSI connector terminal ends. Refer to SI for repair procedures.
    2. For very intermittent issues, check the BTSI wire harness individual circuits for broken or crimped wires. Refer to SI for repair procedures.
    3. Inspect the routing of the wiring harness leading to the BTSI connector. The illustrations above show the BTSI harness routed incorrectly.
    4. Reroute the wiring to create available slack and avoid future occurrences.

    All that being said, I believe you best chance of getting it out of park right now, would be to disconnect the linkage underneath the brake master cylinder and manually shift the vehicle into neutral, then you can have the vehicle towed. All you should need is a flathead screwdriver and a bit of patience.

    reply to corporalm:

    I agree with everything mentioned exept for the last paragraph. The car can be taken out of park and shifted without any tools. From the passenger side of the counsel starting on the bottom front edge, while pulling out with one hand carfully, slide your other hand up in the area at the bottom of the shifter. There is a release button that can be pushed in that will release the pin making it able to shift.
