Not trying to be smart but have you tried it on a battery? I had a solenoid on a 53 trans I picked up that I thought was bad, after finding a replacement I tried the old one on 12v and it worked ever time. Someone in the past had replaced the 6v with a latter 12v solenoid. The one I'm using now is a delco, as long as the shaft length is the same all manufactures should work.
