speedometer problem

i believe my speedometer cable is broke. the speedometer and odometer both are not working. i'm not exactly sure on how to replace the cable. i know
that it is hooked into the transmission somehow but don't know how to replace it. if anyone could tell me how to replace that cable i would greatly appreciate it. thanks

If someone could tell us what kind of vehicle you have, that would be greatly appreciated, too.

Okay... in that case, you don't have a spedometer cable. It's electronic. The signal that drives the speedo/odometer comes from the rear-wheel speed sensor, located on top of the rear differential. Remove the electrical connector, then remove the bolt holding the sensor down. Twist and pull on the sensor to remove it (it's got an O-ring on it, so it's a little bit of a tight fit). Try cleaning off all the accumulated crud on it (it's magnetic, so it attracts lots of sludge from the differential), and put it back. If that doesn't do it, you'll need a new sensor. They're not that expensive (about $35).
However... if you have 4-wheel anti-lock brakes (easily identifiable by an electrical wire running in parallel with the front brake hoses going to the calipers), and you do NOT have illuminated 'BRAKE' and 'ABS' lights on the dash, then the problem is either in the wiring between the ABS computer and the PCM, or something wrong with the PCM or instrument cluster itself.
If you only have the rear-wheel anti-lock (ie. no wire running alongside the front brake hoses), then the most likely culprit is a bad rear wheel speed sensor.
