hello all. I have a 1974 144 fuel injection and auto transmission. My question is this. When I start the car it blows the transmission dipstick about 4 inches out of the tube. Doesn't do it all the time, but more often than not. Secondly once in a while, from a dead stop car will not shift out of first, while spraying transmission fluid out of filler tube. I check the fluid regularly and have not overfilled, the fluid itself is not burned and in good color. The chilton manual says I might have a clogged breather vent (I have no idea where to look for that) any other ideas would be helpful. I do most of my own mechanical work and slowly restoring the car.
