This information applies to the 2007-09 Acadia and Outlook and the 2008-09 Enclave.
IMPORTANT: Every time the shifter knob is serviced, the tip of the actuator rod and the top half of the exposed actuator rod toward the rear of the vehicle should be lubricated (fig. 16).

When replacing a shifter knob on these vehicles, the tip of the actuator rod and the backside of the exposed actuator rod need to be lubed with a special lubricant now available through GMSPOÂ (fig. 17).

p/n 88861426 | U.S. |

Ensure that lubricant is applied whenever the shifter base is replaced, the shifter knob is replaced, or the knob is removed from the shifter base to ensure proper operation of the knob button.
