I followed the FSM diagnostic procedure. Tested the wiring for a short, none. Tested the resistance of that solenoid, should be about 13 ohms, and it reads about 3. I picked up new orings and a cover gasket from the dealership, and I'll remove the valve body tonight (I'll do the other test while it's out to test the short section of wiring that goes into the trans then). New solenoid is scheduled to arrive tomorrow. I'm hoping to drive it to work on Thursday, and her rental car has to go back on Friday.
