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

vent
 
The vent is on the top side of the transmission...

The only 2 things that i know of that cause this problem,,,as you stated blocked vent and also over heating... Do you have a temp gauge in the transmission??

Keith:

Do not have temperature sensor located on transmissiom. But did add a external cooler other than one in radiator. Do you know where breather vent is located?? THANKS... DAVE

We did find Pressure Relief Valve. It is located on top on rear tail section. It is like a pop up valve being a small cap retained over a 3/8" small extention. Removed, cleaned out pipe ( wasn't really plugged) but after driving it did not push up dip stick... Maybe just maybe it might have solved problem... Will keep you posted.... THANKS.... THERESA :)
