Could be the VSS (Vehicle speed sensor)For starters have the PCM (computer) scanned for codes, Autozone will do it for free. If the PCM sees a problem it will store a code that will help in diagnosing the problem, get back with the exact codes.If the PCM doesnt see the truck moving (speedo) it wont let the trans shift
