I want to completely drain everything and I have run into a strange problem. There seems to be no converter drain plug on my 2001 F350 7.3 truck. I have turned it all the way around and did not see anything. What to do - drill a hole and thread it for a plug?

There is a procedure to replace all the fluid by disconnecting the return line from the trans cooler where it goes back into the trans. Slip a clear hose on the hard line and route it into a bucket. Crank engine and cycle thru all gears until fluid quits coming out. Add 6 quarts. Repeat until fluid is a clean red color coming out of hose. This will cycle new fluid thru torque converter as well as the trans. Takes about 18-22 quarts if I recall correctly. Search this forum for detailed instructions.

No one cares how much you know when you are a jerk about it.

I completely flushed and refilled the F350 7.3 truck. The fluid smelled terrible and there was a lot of metal in the pan. Still slips in 1st and 2nd gears. (My F250 V10 transmission drained OK with good-looking fluid, so that transmission should be fine)
I am still trying to make sense of this episode, given the history of the vehicles and no transmission heating problems like this ever occurring before, even in harder, longer trips. Could the ATF break down with time and use, ultimately causing heating issues? Each truck had 30,000 miles or less since I changed the ATF and filter. And of that mileage no more than 2,000-3,000 miles of heavy towing (gooseneck trailer).
I have the shop manuals and in looking through the transmission R&R I don't see much in the way of special tools required, except for a little clip to prevent the converter from falling out. It says to remove and discard the flex plate bolts, so I assume these are not reused. Since I am in a remote area I have to have everything that is required to do the job on hand.
