OD or just Drivemaster?

Sure you don't have the clutch-only Vacumotive unit?



If so, the thing is the governor which prevents automatic clutch disengagement when in high gear at speeds over 20 mph



There is a good treatise on the unit with pics of the governor in the back of the Hudson Mech Procedures Manual for 42-47.

The only thing I can tell you folks is that the original owner paid extra for the Drivemaster option and the Drivemaster on/off switch is in the dash and the Drivemaster emblem is on the trunk lid. There is a big coffee can looking thing that mounts over the engine with wires coming from that "boot" thing mounted to the rear of the tranny and some other wires coming out of some solenoid below the front of the canister over the engine (Dan had posted some pics I sent him on some earlier thread-don't remember which one though).



My manual says the Drivemaster is basically supposed to give you the option of automatically shifting the car (Drivemaster on) or manually shifting (with the Drivemaster shut off). I believe it does use some kind of governing since shifting automatically seems to be done by letting your foot off the gas pedal.



Seems like a much too complicated set up and I'd be curious how well it even worked and how rare the set up was or do most guys just toss them in the trash!



Beyond that.......I have no clue! :-)
