There is a technical service bulletin on this subject. That just means this is a common problem with this car. Code numbers include p1754, p1759, 1764, p1769, and p1774. It says to check for damaged plug or wires, and for damaged pins where it plugs into the transmission. Id start there. It says then if theres no damage to the wires or plug, then, indeed, replace the valve/control body
