If its 4wd do you t-case while you are there. Its only a couple more qts. Also replace a qt of atf in the trans with lucas trans fix. Its will help the bands and clutches

Lucas trans fix, ok will do. You know back when it was cold it wouldn't shift into high when below 50. Had to pull over set there for 20 seconds and take off and it would shift just fine the rest of the day.
