1968 C4 transmission question.....

[Rev]

Dextron is definitely wrong. This guy doesn't know his A$$ from his drain hole. Drain the tranny from the pan. Then drain the torque converter from it's own specific drain plug. Then put in FORD type F tranny fluid, shifting into all ranges until full of TYPE F. If it still leaks, then look for where it does specifically leak. Don't over fill, that's the area wher DUMBO was correct.
My $.02.
