ABSTRACT:
An improved solenoid valve harness assembly for a vehicle transmission is disclosed that is more reliable, less costly to manufacture, and easier to test. In one embodiment, the solenoid valve assembly includes a plurality of solenoid valves and a harness. The harness includes a plurality of conductors for electrically connecting the plurality of solenoid valves to a controller. The harness is connected to the solenoid valves by a plug and receptacle arrangement that reduces the cost of manufacture and that allows each component to be separately tested prior to being plugged together. In one embodiment, the plug and receptacle arrangement permits the solenoid valves to be disconnected from the harness so that a defective component can be replaced without discarding the entire solenoid valve harness. In a further aspect, a solenoid valve harness is provided in which the solenoid valves are internally grounded thereby eliminating the need for ground wires from the solenoid valves.
