Repair Instructions

Step 1: Replace the Vehicle Speed Sensor (if necessary)

1. Disconnect the Battery

   • Before working on electrical components, disconnect the negative battery terminal to avoid any shorts.

2. Locate the VSS

   • The VSS is usually located on the transmission. For the Silverado 1500, it is placed on the side of the transmission.

3. Remove the VSS

   • Use the socket set to remove the bolt securing the VSS.
   • Carefully pull the sensor out of its housing. Be cautious of any transmission fluid leakage.

4. Install the New VSS

   • Apply a small amount of transmission fluid to the O-ring on the new VSS.
   • Insert the new VSS into the transmission and secure it with the bolt.
   • Torque the bolt to the manufacturer's specifications (check service manual for the exact torque).

5. Reconnect the Wiring

   • Plug the electrical connector back into the VSS.

6. Reconnect the Battery

   • Reconnect the negative battery terminal.

Step 2: Check Instrument Cluster (if necessary)

1. Remove Instrument Cluster

   • Carefully remove the dashboard trim panels around the instrument cluster using screwdrivers and trim tools.
   • Unscrew and carefully pull out the instrument cluster.

2. Inspect Connections

   • Check all electrical connections at the back of the cluster for damage or corrosion.
   • Ensure that all connectors are firmly seated.

3. Test or Replace Instrument Cluster

   • If you have access to a known good cluster, swap it in to see if the speedometer works.
   • If not, consider taking the cluster to a professional for testing or replacement.

4. Reinstall Instrument Cluster

   • Once repairs are made, carefully reinstall the instrument cluster and reconnect the trim panels.

Final Steps

1. Test Drive the Vehicle

   • Start the vehicle and take it for a test drive to ensure the speedometer is functioning correctly.

2. Clear any DTCs

   • If applicable, use the OBD-II scanner to clear any stored trouble codes.

3. Monitor for Recurrence

   • Keep an eye on the speedometer and check for any warning lights on the dashboard.
