I'm thinking this is impossible but....
75 B210 A14 Auto. The tranny has been leaking or loosing fluid with no huge puddles only a minor drip from the weep hole. So I check the oil the other day and there was like 3 gallons of fluid in it. There was so much in it the pistons must have been floating. I drained and refilled under to the full line and I just checked it and it was over the fill line. I only found one possibility online, does this sound possible?

THE PROBLEM IS VERY SIMPLE ----yOUR TRANS HAS A VACUMME MODULATOR ON IT --ONE OF THE FEW THAT STILL DOES--- ANYWAY THE MODULATOR IS BAD AND THE FLUID IS BEING SUCKED UP OUT OF THE TRANS AND INTO YOUR CYLINDER CLOSEST TO THE VACUMME--THIS WILL WASH OUT THE RINGS LETTING THE FLUID DRAIN INTO THE OIL PAN ---AND ALSO WILL CAUSE YOUR VAN TO SMOKE AS WELL AS MAKE THE TRANS STOP PULLING WHEN IT GETS LOW.
