Hey all, I have decided I will no longer wait for my mechanics and spend cash on their services. I will do this myself! Now I've eliminated the first culprit, the VSS itself. It was replaced and when it was showed no signs of wear. DTC 452 did not go away and the speed remains dead. Car still had a flashing O/D light. Now I have to check the wire, the PSOM, and the PCM, correct? What tools will I need and how do I do it?
