On my lokar Nostalgia, had many problems just getting the presets correct, and also a sticky button. In my case the threads holding the knob didn't go down the shaft far enough to seat the knob properly. Had to tap it a little further, to allow the button to fully disengage and not stick. Most people don't seem to have problems with their shifters, but mine required a bit of customizing to dial it in(after following instructions to the letter!) Maybe it's just a Ford c-6 thing!
