I recently installed a used gearbox into my car. Everything works fine about it, except that I when I am in first gear it makes that sound that gearboxes normally make when they are in reverse. I actually kind of like it, but I thought I would ask if this is a sign of something about to go seriously wrong. BTW, why do gearboxes sound different in reverse?

Doc, correct me if I'm wrong, but my understanding is that strait cut gears are louder because there is nothing to control the thrust. I.E. Helical gears push the gear and shaft to it's endplay limit. Strait cuts don't so they float and cause a whine. If it sounds the same, I'd think you have a thrust issue on that gear. Is there some kind of thrust bearing or something on 1st gear, doc?
Mark D. P.S. My new engine has strait cut cam gears... Sounds awesome! |
