Holy crap I'm glad I found this thread! I tried like hell to get the stock shift knob off...even rigged up a lever and moment arm (2x4) and almost destroyed the collar just below the knob..I called Torq Speed Lab, Hurst, and they all said "it just pulls straight up"
Did GM change this in 2013? Got mine installed in about 2 hours as well. Getting ready to drive it here in a few.
Thanks for posting up how to take that damn shift knob off!
