Ready to chuck the thing! I bought a brand new GM shift handle, sounds like an easy fix, boy was I wrong! I have sanded the inside, used an exacto knife, trimmed the heck out of it. I finally got it on all the way and now the button does not allow me to shift it in and out of gear. Its like its not pushing the whithe button all the way down. What am I doing wrong? What can I do to fix this problem? Should i just buy a billet handle and forget the stock one? Any help is appreciated!
