As others have said, there's not really anything you can do about it. Drive it until it doesn't anymore.

As for your oil change, there is a drain plug in the torque converter as well. You have to spin it around until you can take it out through the little grille on the bellhousing. You'll get another 2-3 quarts out of that for a more complete fluid change.
