SWAPPING SHIFTER HANDLES ON THE NBS TAHOE
@Bear77
Should be a single T30 screw with some blue thread locker from the factory.
Just go slow and it will crack loose. Keep that steady pressure on the driver and remove it so as to not strip it. Make sure and thread the orange cable back to the plug exactly the same way, in and out installing the 2 nylon clips where they go. I took a before picture to reference because twice I did it the wrong way because I was in such a hurry. Lol
A little help that I did not know is the the tilt level just pulls straight out with a firm grasp which will allow you to remove the upper and lower plastic pieces of the steering column. There are 2 hooks nearest the DIC that hold it together so don't go just yanking it apart and some other miscellaneous placed male and female tabs on both sides where it separates that clip back together during reinstallation.
My 06 does not have any screws in the bottom of the column. I say that as I came across an OBS thread on this and they had a few screws in the bottom of the column plastic. I did remove my dash bezel as well and the lower trim piece just below the steering column (2 x 7mm bolts IIRC and 2 push tabs at the top to get it off) just to get better access to the plug as it is taped to the ignition wiring. Small flat blade screwdriver will separate the male and female ends.
Figured I might as well do a short write up as I was pressed for time and didn't take a ton of pictures the day I put it on. Hope that helps you out and anybody else who had those questions.
