Truck speedometer quit working suddenly with harsh erratic trans shifts. This is common to big Fords with a common speed sensor in rear differential. 90% of the time either sensor or this pigtail go belly up as both are in a constant bath if slop. Replaced both and fixed the problem. These parts identical to originals at like a quarter the cost.
