  Q: How to replace the Shift Knob on Buick Enclave?

  A: The first step for enclave Shift Knob replacement requires you to activate the parking brake before removing the floor console left extension panel. Tap up/tap down transmission switch connector must get disconnected while having the key turned to run mode with the auto start function disabled. A flat-headed tool should be inserted underneath the trim ring of the Shift Knob while moving the lever backward to create a space for separating trim ring pieces. Downward pressure will free the ring pieces from the knob which will lower 13.0 mm (0.5 in) below to show the knob retainer screw. Proceed by removing the Shift Knob screw then guide the transmission tap up/tap down switch electrical harness and connector through the shift control indicator while taking out the Shift Knob.
