You're going to try and melt it off? I would saw it before I would try something like that. Cut down off center from top to bottom enough to be able to crack it with a chisel, the same way you would chisel cut a stripped nut on a rusted bolt. Use a power rotary saw to weaken it enough to break it away. This will leave it clean and ready for a new knob. Wire wheel off whatever glue they used. Even if you saw into the shifter no scarring would show once you put on the new knob. Treat it like an Apple. Just cut it apart....SIMPLE.
