my speedometer does not work on my cluster, i have replaced it once and speedometer still didn't work so returned it. i then replaced the sensor on my rear end that deals with my mileage/speed. today i also replaced my transmission speed sensor gear that goes on the side of my transmission. i was told that if i took the sensor out and spun the gear with the truck on but not cranked and the needle moved to replace the gear because the teeth are worn well i did that and it still doesn't work so now i have no idea what to do. PLEASE HELP.......
i have also looked at the gears inside my transmission and i cant see any problems with the teeth on them plus they are medal and was told that they are way less likely to go bad.

DTC P0500: VEHICLE SPEED SENSOR (VSS)

1. Check Input Signal Circuit - Turn ignition off. Disconnect ECM harness connector and combination meter harness connector. See Fig. 1. Using an ohmmeter, check continuity between combination meter harness connector terminal "7" (White/Blue wire) and ECM harness connector terminal No. 26. See Fig. 2 and Fig. 21 . If no continuity exists, repair open in Yellow/Green wire. If continuity exists, go to next step.

2. Check Speedometer Operation - Check speedometer operation. If speedometer does not function, disconnect VSS harness connector. Remove VSS from transaxle. Check resistance between VSS connector terminals. Replace VSS if resistance is not 250 ohms. If resistance is 250 ohms, go to next step.

3. Set voltmeter on AC scale. Connect voltmeter to VSS connector terminals. Turn VSS pinion gear to generate voltage. Voltage should generate to about 0.5 volt. If resistance and voltage are not correct, replace vehicle speed sensor. If VSS unit is okay, check ECM connector terminals for corrosion or damage. Repair as necessary and retest system.
