Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Could this possibly be part of a larger problem? Seems like everytime this problems happens the tranny will not shift out of 2nd gear. I stop, turn off the vehicle, the cluster turns on again and the tranny works fine until the cluster dies again a few miles down the road.
If transmission happens every time cluster stops working that would mean you have a loss of power, loss of ground, or data wire is shorting out. The pink wire is ignition power, the black/white wire is ground, and the gray wire at pin A5 is the data wire. If power/ground is good I would bring it to shop for data wire to be diagnosed because it could also be a module shorting out on data circuit. Let me know if you have questions or if there is anything else I can do to help. Thanks.
