Subject: Various Concerns With Shifter and/or Ignition Key (Replace Shifter Assembly/Shifter Components or Ignition Lock Cylinder )

Models: 2005-2007 Chevrolet Cobalt, 2005-2006 Pontiac Pursuit (Canada Only), 2007 Pontiac G5 with Automatic Transmission 4T45-E (RPO MN5)

Condition

Some customers may comment on any of the following concerns:

• The shifter is hard to move or binds.

• They cannot remove the ignition key.

• It takes high effort to rotate the key.

Cause 1

The shifter button may be sticking in the handle.

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 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 Knob Replacement in SI. Download File PDF
