(USA I > guess) Um, he's trying to fix it, isn't he? But, the law is "don't speed", having defective equipment will add to the penalty, maybe, but isn't something you'll get busted for in and of itself. If you use, for instance, a GPS to keep from speeding, I don't know of any states where anyone would care. > Plus if your speedo don't work then you're not recording mileage are you? That'd be a good troubleshooting step. Is the odo working, or are they both broke? If both are broke, it's between the tranny and the instrument. If miles are rolling on the odo, but the speedo doesn't move, it's the instrument itself. > My speedo needle bounces at very low speeds, almost as if only a couple of > teeth on a gear working... There's no gear, it's a needle in a drag cup. Kinked cable can give you what you describe, and if it goes long enough it will also damage the instrument. Been there, done that. Dave Hinz
