    No Power to Speedometer?

    1992 C1500 with the 700R4 here. So I've had an intermittently working speedometer, most days it's just totally dead no matter what speed you're going, and if I'm lucky enough to hit a serious pothole it comes back briefly. Started by replacing the VSS and its pigtail (the old wiring was soaked...

    Lost Speed Signal to Dash

    I have an 88 dash and harness I swapped into a 96 K3500. It was a shell I got cheap so I put an LQ9 and 4l80/np241c in it and used the interior from a derelict 88 k2500 I had. I deleted the cruise control when I moved everything over because I couldn't really use it, but I have not had a working...

I’ve been getting by with my autel scanner and facebook for years but I think I’ll be needing some help with this one. I just picked up a 1994 C1500 W/T (4.3L 5-speed) which...

    Speedometer reading MUCH too high..

    I recently acquired a '96 Silverado z71 4wd and the speedometer is reading at least double what it should. I have replaced the VSS and the instrument panel, but neither made any difference. If I understand correctly, this truck has no DRAC/VSSB module and the VSS signal reports directly to...
