P0657 what wires and pins to test?
I have a 2005 F350 6.0 Utility Body Work Truck that is shifting hard into gears from park. Pulled code P0657 and began chasing the trans harness and connectors for damage from the PCM to the trans, but no visible damage. What pins/wires do I need t test for voltage? Colors and pin numbers would be a great help. Thanks
