Question about GMC Sierra 2500
I just had the same problem. My speedometer was jumping up and down randomly, then would die completely...followed by all my other instruments. I thought i had a bad ground and spent hours looking. Soon followed a shifting problem where my it was not auto shifting. I had to manually change from 2-3, with no first gear. I immediately thought ground problem on the tranny. No luck again. Took it to have the codes read, which pointed to all shift solenoids, but i knew that could not be it. I was still set on a bad ground.
Took it to a transmission specialist to see if he had heard of the problem. He took a look and said it was the ignition switch. I though, how the hell does that have anything to do with...instruments....shifting...some many problems. Sure enough, i replaced and it runs like a champ. Hope this helps.
