Default Re: 1951 Ford overdrive

I have the original R10 BW overdrive which was installed at the time of the factory build. As noted in the above posts, I have been unable to engage the overdrive in spite of now adding a new solenoid, new relay, new wiring harness , and new kick down switch. The governor is nos and was installed during a professional transmission rebuild. With the OD cable pushed in, the transmission freewheels normally. When 30 mph is reached and the gas pedal is momentarily released, no shift into OD takes place. In Randy Rundle's Overdrive Manual, the governor is tested by removing its cover, separating the points ,and grounding the cover. Unfortunately, on my car there is insufficient floor pan clearance to be able to remove the cover screws to accomplish this test. BTW, with the key on, both the relay and the solenoid click simultaneously when the TH terminal on the relay is grounded. I have ordered a proper sized wrench to remove the governor should that be necessary. I would appreciate any other suggestions for an alternative means of testing the governor without the necessity of removing it. Also, does anyone know what type of nylon (??) gear is attaches to the governor"s shaft? Thanks in advance for any suggestions.
