Ok so I am an issue with my cluster. My speedo and odo do not work at all. My tac jumps around and doesn't rise and fall smoothly and my trip odometer moves but it is very incorrect. It will move maybe 1/10th of a mile for every 20 to 25 miles. Any Ideas on what it could be. I have checked my VSS and the gears in the back of the cluster and then replaced both. Is the cluster bad or is it something else. Thanks for the help.

Post does not state the model year of your car.

The fact that the speedometer and the odometer is affected says that the problem is in the cluster itself or the VSS sensor. How to narrow it down?

Use an ODB2 scanner to ask the PCM what the speed is.

If the PCM is correct, then the problem is in the cluster.

If the PCM is wrong, then the problem is in the VSS sensor.
