Ford C3 Blowby ??
We have a Shay ( Fibergalss reproduction of 29 Ford Roadster) that has a 1979-80 Pinto drive train with 2.3 Liter four banger with automatic C3 transmission. I have had problems on highway with blowing out transmission fluid. It will push dip stick up and out of tube about four inches, which leads me to believe that a vent must be plugged?? Do you know where vent is located on this transmission? Or what else could be causing this problem? We have installed an external cooler but condition still seem to be there?? Any suggestion would be appreciated... THERESA
