Default do-it-yourself transmission fluid flush?

I went to the Auto-RX website, and noticed that it's possible to put
Auto-rx in the transmission too. And from the instructions, it seems
critical to flush the auto-rx out after it's finished treating.

For Do-It-Yourself Mechanics Only (technical expertise required)

If you are willing to do it yourself here's our recommendation. Install
6 oz's of Auto-RX and run 1000-1500 miles to clean the transmission.

THEN drop pan, change filter, reinstall. Measuring the old fluid in pan
into a milk bottle type container, install that amount of new ATF back
into transmission. Disconnect BOTH ATF cooler lines at radiator and
place a container or pan under each line end (helps to have an
assistant). Start engine, shut down after 1 or 2 quarts have come out
one of the lines. Refill exact amount of fresh fluid in transmission
(this keeps air out of the system).

Start engine again and repeat until clean fluid is coming out of cooler
line. This is messy and time consuming but will purge all old ATF from
transmission and torque converter. Reinstall cooler lines and start
car, cycle through gears, place in park and check level per owners
manual. Check for leaks. Top up as necessary after driving and heated
up. Don't overfill.

You just safely flushed the whole system, no T-TEC $ cost and Auto-RX
has removed the dirt and contamination from your transmission.

A few comments though:

Wouldn't this leave some coolant inside the radiator?

To remove the coolant from the radiator, it makes sense to disconnect
only ONE ATF cooler line from the radiator. One end should be the
suction, and the other should be the drain.

Let's say you disconnect the ATF cooler line on the RIGHT side. (Right
side from looking at the car from under the hood.) The metal tube
leads to the tranny, and the rubber hose leads to the radiator. Would
the coolant be pumped out from the metal tube, or from the rubber hose?

Would it be safe to simply run the car, put a gallon of ATF on the
suction end, and collect the old ATF until it runs clear into a basin?

its messy, time consuming, and on a older car might do more harm them good.
Why bother?

You can harm it by moving the crud around to where it is not presently,
Pull the pan , clean the magnets and replace the filter, if fluid gets
dirty change it when its dirty, dont wait.

personally, I would not use auto-rx in the transmission.
transmission fluid already has a high concentration of detergents
just keep your existing fluid clean by draining more frequently - that
way you have no worries about getting the auto-rx out after use
