Another interesting thing is that you can install a "manual override" switch to override the automatic features. Best of both worlds, I guess. As for the upshift while freewheeling--- perhaps an experiment is in order. To 38Coupe's point: Yes, the engine speed has to drop, but if you are freewheeling I'll assume the engine is idling and you haven't lost your brakes. I've got a nice 5 mile downhill run to try this on.
The first time I drove my 57 to work I forgot about the freeweeling. I stopped at the grocery store on the way home. When I got out, the car started to roll away!! I was able to slow it down and get back inside before it hit anything.
Depends on the transmission, mine has a reverse lockout when overdrive is engaged. (freewheel) That is why my emergency brake works so well. Posted using the Full Custom H.A.M.B. App!
I was raised up in western Kansas so most overdrive operation in our old 51 Merc was on the flats. We did occasionally travel up to Denver Co. When we got into the hills, the lock out handle was pulled out so that we could use the engine as a brake going down hill and no overdrive for climbing. Leaving the overdrive system engaged in mountain country can get you in a world of hurt. It's also hard on the brakes.
Not sure I this link will work but was very helpful in understanding these overdrives. I've got one in a 49 Cosmo and it works great. http://www.fordification.com/tech/overdrive.htm Posted using the Full Custom H.A.M.B. App!
Sorry for the late post, these two pictures are the individual components of the governor on my '69 model. As above my friend machined a new piece from a small piece of Micarta.
