Ok. This is a pretty open question, but, here goes. If we are talking about your 2000, or newer silverado, you better start by having your Chevy dealer run what is called a "vis", on your "vin". lol. A vis is a vehicle inquiry system, a system that GM uses to track open campaigns, re-programs, and recalls. There was a glitch in the above mentioned Silverado odometer, and speedo, as well. Check it out. Note, if you are driving that Silverado, depending on the year, there may be a bunch of other open campaigns on that truck, as well. One for the tailgate straps, the steering column, and several others. If it is any other vehicle, I must urge you that odometer tampering is a crime. You must have a qualified shop, or dealership, handle that for you, unless it is a classic car, in which case I would say just buy a new one.
Need to figure out what's wrong with them, first.
Unless you can find a rebuilder on the web then you can have the dealership send it off for repair. You could also look for one at a junk yard.

Odometer readings are displayed from by data relayed by the PCM. It is fully electronic and can only be manipulated by a specialized licensed repair facility. The Gauge cluster also has a built in memory so even if the PCM is changed it will not adjust the odometer display.
It means odometer.
See answer for same question on 2004 Chevy avalanche. JIT
Odometer tampering is an illegal practice and a serious crime. So it might be better for you to see an authorized dealership to have anything done with your odometer.....
yes? and why?
Look at the odometer, it will tell you what mileage it has.
What would make your speed odometer stop working after putting an alternator on? 2005 Chevy Malibu
Yes.
If both the odometer and the speedometer do not work it may be the speed sensor in the transmission is bad. If only the odometer does not work it is probably a bad cluster.
