2000 Chevrolet 2500 Pickup Question: speed sensor 2005

The problem is usually the vehicle speed sensor (VSS) or could be a malfunction in the instrument cluster, in either case some basic tests need to be done to determine what has malfunctioned before just replacing parts. If the VSS failed you also loose cruise control so see if cruise control has also failed.
