if the govenor works (puts out a ground signal at 28mph), the relay works under control of the govenor and solonoid works under control of the relay and the OD unit works on the bench then when driving over 28 mph and you hear the relay and solonoid energize, just back of the gas and you will feel the unit drop into gear and feel a little compression braking untill you accelerate. if you dont hear the relay operate check all your wireing by tracing one wire at a time... that is exactly how mine works in my 53 car.... i have owned 7 cars with ODs and have found all kinds of crazy stuf wrong with the wireing. even has a weak relay that would not energize teh solonoid and a bad ignitions switch that would not pass enough current to operate teh solonoid... PM me with a phone # and i can talk with you if you wish. the transmission always worked after teh other problems were sorted out....
