• Q: How to Change the Shift Knob on 2008 GMC Acadia?

  A: The first step to changing the acadia's Shift Knob involves applying the parking brake followed by removal of the floor console left extension panel. Disconnect the transmission tap up/tap down switch electrical connector then rotate the key into run position without engine activation. A thin flat-bladed tool should be gently inserted between trim ring and Shift Knob layers to ease the trim ring off the Shift Knob because these pieces will separate by approximately 13.0 mm (0.5 in). Only after screwing out the Shift Knob screw can you safely guide the transmission tap up/tap down switch electrical harness and connector above the shift control indicator when removing the Shift Knob from the shift control lever. To assemble the Shift Knob users must apply p/n 88861426 lubricant to the shift control lever tip followed by proper electrical harness guidance when putting the Shift Knob in place onto the shift control lever. Secure the knob screw by tightening it to 4 n.m (35 lb in). The Shift Knob trim ring needs lifting until you hear a clicking sound to show proper mounting to the Shift Knob. After this set the shift control lever to park position and turn off the key. Check the transmission tap up/tap down switch electricity and verify shift control operation through all ranges before installing the floor console left extension panel along with brake release.
