2006-2010 Chevrolet HHR
2005-2006 Pontiac Pursuit (Canada Only)
2007-2010 Pontiac G5

Supercede:
This bulletin is being revised to update the Warranty Information #4. Please discard Corporate Bulletin Number 06-07-30-004F (Section 07 - Transmission/Transaxle).

Important
When servicing a vehicle for any type of shifter/key concern, please perform the following initial inspections prior to replacing any parts. - Verify the electrical operation of the ignition lock cylinder solenoid. Refer to the Ignition Key Can/Cannot Be Turned Off With Transmission in Any Gear in SI.
- Verify the adjustment of the automatic transmission shift cable. Refer to the Shift Control Cable Adjustment procedure in SI.
- If these initial inspections do not resolve the customer concern, check the potential causes listed in this bulletin.

Condition #1 (2005-2008 Cobalt, G5 and Pursuit Only)

Some customers may comment that the shifter binds.

Cause #1

The cause of this condition may be the shifter button sticking in the handle.

Correction #1

Verify that the shifter button is inoperative by evaluating if the park pawl pin on the shifter assembly moves when activating the button. If the parking pawl does not move when the button is activated, the shifter handle will have to be replaced. Refer to Floor Shifter Control **** Replacement in SI.

Parts Information #1

Warranty Information #1

For vehicles repaired under warranty, use:

Condition #2 (2005-2008 Cobalt, G5 and Pursuit Only)

Some customers may comment they cannot remove the ignition key.

Cause #2

The pin that activates the micro-switch may have moved out of position (refer to illustration above). This causes the micro-switch to fail to engage when the vehicle is placed in Park. If this condition is present, the customer will not be able to remove the key from the ignition.

The illustration above shows the switch in a correct position.

Correction #2

Important
A change has been made to the shifter assembly for service. The replacement shifter assembly will read PRNDIL (Park, Reverse, Neutral, Drive, Intermediate and Low).

Verify that the micro switch is out of position. Replace the shifter assembly. Refer to Transmission Control Replacement in SI.

Parts Information #2

Warranty Information #2

For vehicles repaired under warranty, use:

Condition #3 (2005-2008 Cobalt, G5 and Pursuit Only)

Some customers may comment that the shifter is hard to move.

Cause #3

The slider may be binding in the guides. This may cause the shifter to become difficult to operate.

Correction #3

Replace the slide indicator and guides in the shifter following the procedure below:

1. Apply the parking brake.
2. Remove the upper console trim. Refer to Trim Plate Replacement-Console Front in SI.
3. Remove shifter ****. Refer to Floor Shifter Control **** Replacement in SI.
4. Remove the indicator plate. Use a flat-bladed screwdriver to release the locking tabs.
5. Remove the shifter indicator lens.
6. Pull up on the indicator and remove it from the assembly.
7. Remove the two front rails by unsnapping the front and lifting up, and then back, to remove the rails from the shifter assembly.
8. Install the new guides. Place the hook end into the assembly and push down. It will snap into place.
9. Install the new slide indicator. With the transmission in neutral, place the slide over the shifter and into the guides. Move the slide indicator down the guides in the front and rear.

Important
Replace the shifter indicator lens if damage is present due to the slider binding or if it becomes damaged during disassembly.

10. Install the shift indicator lens.
11. Install the shift indicator plate.
12. Install the shifter ****. Refer to Floor Shifter Control **** Replacement in SI.
13. Install the upper console trim. Refer to Trim Plate Replacement-Console Front in SI.
