CHEVY SILVERADO 4X4

2002 Chevrolet Truck • 6 cylinder 4WD Automatic • 114,000 miles

These are the codes that showed up for my 2002 Chevy Silverado: p0785, p0758, p1860, p0740, and p0753. Can you direct me in a direction to start at? Also my gas hand, speedometer, cluster lights, are not working.

Those are all transmission codes, take it toa trans shop. Also check to make sure your battery is good as that may be the cause of your gauges not working.

Thanks, I have replaced the battery and transmission shop said it was the ignition switch in the steering column so I bought a new one. It worked good for a couple months but here I am again with same problems.

It may be a bad connection at the trans or broken wire, this would need to be physically looked at for repair

Check and see if you have power to, and across IGN 0 fuse in the left fuse block. If you do, clear the codes and see if the condition still exists. If you do not, replace the ignition switch. It supplies power to IGN 0 fuse, and subsequently all the solenoids in the transmission.
