GM key and shifter concerns

Customers may complain about one of several concerns relating to a binding shifter, difficult shifter operation or inability to remove the ignition key. This applies to 2005-2010 Chevrolet Cobalt, 2006-2010 Chevrolet HHR, 2005-2006 Pontiac Pursuit (Canada) and the 2007-2010 Pontiac G5 (all with automatic transmission 4T45-E).


The cause of a shifter bind may be traced to the shifter button sticking in the handle. 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 pin does not move when the button is activated, the shifter handle must be replaced. Refer to Floor Shifter Control Knob Replacement in the service manual.

Some customers may complain that they cannot remove the ignition key.

The pin that activates the micro-switch may have moved out of position. This causes the micro-switch to fail to engage when the vehicle is placed in Park. If this condition is present, the customer cannot remove the key.

Verify that the micro-switch is out of position. If so, replace the shifter assembly (refer to Transmission Control Replacement in the service manual). NOTE: A change had been made to the shifter assembly for service. The replacement shifter assembly will read PRNDIL (Park, Reverse, Neutral, Drive, Intermediate and Low).

2, Remove the upper console trim. Refer to Trim Plate Replacement – Console Front in the service manual.

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.
