727 Trans Fluid Capacity

I would fill the convertor with about a quart of fluid and then a thin coating on the snout. Carefully slide it into the tranny making sure it is seated all the way. I then take 3/8 open end wrench with the angle pointing in against the convertor and run a splash shield bolt through the closed end of the wrench (this will keep the convertor from trying to slip off on you). Jack it up and get it as close to the block as you can and one side or top will probably be closer to the block than another so start a bolt there and SLOWLY pull it toward the block with the other bolts. I think my 727 completely empty took about 9 quarts to fill including the one in the convertor. I started my car for the first time in neutral so the convertor would fill the rest of the way.
