Scott - I've had the console open, removed the solenoid and tested it. 12 volts caused it to activate so I think the problem is elsewhere. Glad you didn't pay for the new shifter, my dealer quoted about $85 for the solenoid and it's a snap to replace, once you figure out how to get those O/D wires out of the connector in the console. BTW that connector is only 8 pins, the one I'm looking for is 16.
Alan - thanks for the tip. There's only about a dozen electrical connectors by the fuse panel, so I guess I need to sort through them carefully.
Anybody have more specific info?
