Hey guys I have a mechanical question. My 05 Silverados speedometer isn’t working properly. It is reading under the speed I’m going, it seems like by about 15-25 mph under what I’m actually going. The speedometer kind of slides in a jerky motion instead of a smooth motion like it used to. At times it seems like it reads correctly, but there are other times it defiently is not reading correctly. What would be the issue here? The speedometer motor itself? Or the speed sensor on the transmission? Thanks for any help.
2005 Silverado speedometer issue?

The stepper motors in the cluster are notorious for going bad. Usually they stick in one spot or don't work at all, so you're problem isn't something I've seen, but that would be my guess. If you know anyone with a GM tech 2, they can do a sweep test on the cluster in order to condemn it. I don't think I've ever had a speed sensor problem on those trucks and I've been a GM mechanic since 2000. Good luck
Thanks. Yeah I was more wondering because the speedometer still works, it is just reading under what I’m actually going. That’s why I wasn’t sure if it might be the sensor.

He hasn't done anything recently, right? Bigger tires, differential work, transmission work?
I replaced the tie rod ends inner and outer and got an alignment.

The clusters on those trucks are notorious. My brother, dad, a couple buddies and myself all changed then out at least once on 03 thru 06 chevys.
