The speedo is electronic, u will have to pull the unit out and send it to a GM authorized repair center like speed-o-tach inc.

I have found that when you are going to engauge 4x4 high, it is best to only be going about 3 miles an hour. Not faster, not stopped. It likes some movement to help it mesh. I've had perfect shifts since I started this. Hope it helps. Wade.

SOURCE: 1989 gmc sierra 2500 problems

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.

SOURCE: 1989 GMC Sierra 3500 loose tilt steering column

Without taking the tilt mechanism off you can only reach 2 of the 3 bolts. If you use 1/4 in. socket on 1/4 in drive with 6 in extension you can just get at the left bolt. If you remove the tilt spring you can get to the bottom bolt. To remoce tilt spring retainer use standard Phillips.

Speedometer on my 2000 gmc Sierra is going haywire, along with ABS light on and transmission is shifting weird. All happened at the same time


Could be the speed sensor on the transmission.
Is the check engine light on ? Have you checked for trouble codes for the ABS ?

2005 GMC Pickup speedometer does not go to zero


There was not a recall, but there was a class action settlement where GM agreed to extend the warranty on certain vehicles for this problem. Check www.gmspeedometerrecall.com to see if you qualify.

I have a 2005 GMC Sierra Pickup and the speedometer stopped working, well actually it goes in between 90 and 120. What do i do?


Your instrument cluster needs to be rebuilt, your speedometer drive motor is wearing out, very common on these trucks.
