Hello all, I suspect the speedometer in my 96 hatchback has been replaced previously, and it is terribly inaccurate. I was wondering if anyone knows what color VSS gear matches which speedometer?

Hmm, so the gear was correlated to the wheels, not the speedo. Any chance the speedos are specific to wheel size? I have the 14" wheels, and a red gear on the VSS. I have also verified via the VIN that I have the original tire size, and that my cluster has the tachometer. I know you can get the tach with an 85 mph speedo, but they seem rare. My speedo is the 120, but it reads low by 7 mph at 20, 4 mph at 30, seems right on at 40, then off the other direction the rest of the way. It sure seems like I should have the 85, not the 120. Anyone have any ideas?
From the description of your speedometer error, the problem isn't the gear ratio. An incorrect gear will give proportionally wrong reading at all speeds, as an example 10% too low gear tooth count at 30mph, 60mph and 90 will give 27, 54 and 81mph readings.
Your description of the "off" readings on your speedometer is pretty close to how mine reads. I would suspect the speedo itself is part of the problem. They age two ways; the spinning magnet weakens with age, which would result in lower readings: and the spring that holds the needle in a specific position also weakens.
Definitely the speedo. It called it quits yesterday. Odometer still churns away, but 0 mph no matter how fast I'm going. Used part on the way. Thanks for your input everyone.
