1956 Mercury Monterey, 3-speed with overdrive
With the OD handle pushed in (engaged) it freewheels just like I pressed in the clutch anytime I lift off the accelerator.  With the handle pulled out (disengaged) it acts like a normal 3-speed.
Followed the troubleshooting guide here: http://www.fordification.com/tech/overdrive.htm
Relay is good I think, I can hear it click when I ground the wire to the governor.  I think the solenoid is bad.  I ran a jumper straight from 12V at battery to the positive wire on the jumper, nothing.  Ground wire is good.
Is there any way to rebuild the solenoid?  Any good source for a replacement?
