is there a way to drain ALL of the fluid out of my tranny? I have by mistake put mercon-dextron in to my 4 speed w/ overdrive tranny ( too many makes of cars in driveway)grabbed wrong fluids from shelf in garage, by the time I noticed what I was pouring, a full quart was in and part of another was left in my hand . Using the drain plug just under the fill on the side looks as if there will still be a lot left in there . Short of dropping the crossmember to pull the bottem plate , is there another way to fully drain the tranny ?
