I have been trying to find a loud noise in our 64 sport fury. If you didn't know better you would think it was something in the transmission making a noise that varies with rpm. While it was making the noise today I happened to be adjusting the heat temp knob and the noise went away. I can make it go away by adusting the slider knob - cold is quiet and hot is LOUD. I can reach down and feel the valve vibrating. Ideas?
