Start the engine up and go through all the gears pausing at each gear for about 30 seconds. With the engine still running and the truck in park or neutral crawl underneath the truck, remove the fill plug and continue adding ATF until it starts coming out the fill hole again. Replace the fill plug and tighten to the appropriate torque. You are now done. If you follow this procedure you should be well below the limit of the trans temp that is not to be exceeded while filling the trans. Remember ATF expand with heat and the hotter the ATF is in the trans the less ATF you will be able to get back into the trans.

I was assuming the poster knew how to replace the fluid and was asking about how to check the level when hot.
Just for the record I change the fluid, drain and fill, 3 times removing the pan all 3 times. I figure I get 90%+ of the old fluid... maybe more.
All fills running the engine and transmission like described. On the third fill I do the more precise level check. All pathways lead to a similar result. Keep on truckin.
