Asked by Jan 30, 2013 at 06:49 PM about the Chevrolet Express

Question type: Maintenance & Repair

The speedometer is going wacky and the transmission is shifting funny. I believe it is a short somewhere but any ideas where to start?

I'd start at the Positive batter terminal. These things can get corroded while you weren't looking and cause connections to go brown. Disassemble all connections to the positive take a brass brush and a little spray cleaner and re-assemble...don't forget to clean the negative ground lug..both ends.

My Mechanic worked on it for 7 hours and found a section of the wiring harness that was inside the inner fender, was resting on a sharp piece of metal, and over the years the rubbing caused it to cut into 5 wires and short.!! money well spent, I would of gone nuts trying to fix that one.
