I have 2002 sliverado 5.3l 1500 4x4 ext cab 4l60e. My speedometer and odomoter are not working. I replaced the vehicle speed sensors and it still didnt help. Then I took it to the tranny shop and had it scanned, the scanner said i didnt have a speed sensor hook up at all. They checked them and they were fine. So i got out my ohm meter and tested from the sensor to the pcm and it was fine. I also tested from the pcm to the gauge cluster plug and the connection was fine there.

So my question is should i get a new gauge cluster or should i get a new pcm? The only reason i am thinking pcm is because it is not reading the sensors.
 
maybe check to see if someone has put a switch in to shut if off. I know you can run a wire to one of the pins on the back of the cluster and put in a switch to shut of the odometer. seen it a few times. It kills the speedometer aswell.
