1955 Muncie 3 speed with electric Overdrive. Clean unit came out of a professionally restored 1955 sedan. I have used the engine attached and it was indeed professionally rebuilt. I have not used the tranny. It has new wiring around the solinoid and OD unit. This uit will solve all your issues about re-gearing your rearend and changing trannt's. Simple GM bolt-in solution, period correct. Not cheap/worth it $600
