What is the best way to drain the torque converter on a 3 speed automatic on a 65 American 440 sedan?

Hub into a 5 gallon bucket. And let ir sit like that for a few days. Unless it haa a drain plg. Alot of older Fords had plugs. Some rebuilt ones did too.
Assuming its out of the car.
In the car?  Does it have cooler lines?  If so...disconnect  one, into a 5 gallon bucket fill the transmission with fluid,  (2 people is better for this)  start the car,  run it, when ir almost stops pumping, turn off the engine, and hook up the cooler line and refill again and check it from there

It is still in the car. I thought maybe there was a way to do it with the converter still in the car.

i had an old nova i did this to.. i took the inspection cover off the bottom and i drilled a small 1/8" hole in the converter.  let it drain overnight. then used a tiny self tapping screw and rtv to close the hole back up.. i drove the car another 60k before i sold it and had no problems.

I have heard of doing that. I am having a few issues with the transmission and i dont want to drain the fluid and then mix new fluid with what is in the converter.

I could not find a reference but somewhere in the cobwebs I seem to remember Amsoil recommending that if you completely changed fluid, you had to drill a drain hole in the converter.  They had a plug that resembled a pop rivet that you then installed to plug the hole.

Its hard to tell if there is a drain plug since it looks like the torque converter is completely covered by the flywheel. I looked through the hole in the bottom of the bell housing where the flywheel is exposed.
