I have a 06 Silverado 1500....my cluster is going bad (stepper motor) and want to replace it. I have another cluster that I can use in place of mine.

Question is will the truck tell the cluster the mileage and hours (via the PCM) or do I need to have it reprogrammed. I always thought the mileage was recorded on both the cluster and PCM.

Any help is appreciated. There is a local place to me and It would take a few days to do, still need the truck though.....
