I'll first check the fill plug to be certain it will come off when I go to fill. if affirmative, I'll drain the transmission fluid. From what I've read, I'll get ~3.5 liters. Now, I'm understanding that the entire transmission holds 9 liters (including the torque converter).
What I've read is that you can run the engine at idle, and in park, for not more than 3 minutes to pump the fluid from the TQ to the pan.
1. Is this correct?
I would measure all the fluid that came out, then knowing how much to return to the transmission (and following refill instructions).
In the alternative... what do you do? Keep filling and refilling until the fluid has been fairly well flushed out? If that's the case I'd use a compatible, but less costly fluid, to do the flush(s).
My primary objective is to get out as much as possible the old fluid, and not just ~3.5 liters.
I need to know if I'm buying 5 or 10 liters of fluid (assuming the 5 liter containers).
Any tips, pointers, or advice is appreciated. Thank you.

Running the engine with the drain plug out of the pan is asking for a dead transmission. There are several Torrington style bearings inside the torque convert alone, which could easily be damaged doing this. Besides which, it won't work very well as the pump pulls fluid from the pan, which would be empty with the drain out, so you would not be moving much fluid out of the converter, just burning up bearing surfaces.
If you want to flush it with clean fluid, you would be reducing your chances of issues.
