I'm NO expert by no means! That said, on one of my Lincolns, I think it was a 1978 model. When I serviced the trans. they dropped the pan to clean or change the filter it also had a plug in the torque converter.(some years have them some don't?)They pulled the plug and drained another 3/5 qts. When back back together the trans. took about around 10/12 qts of trans. fluid.
Good Luck
