Do I need to pull my trans?

I just finished installing an aw4 in my 98 tj. In our adult beverage induced 4 am install nights we forgot to pre fill the torque converter. I have just finished buttoning up some of the loose ends, and have been driving the jeep around town for the past 5 days. It runs and shifts fine. I checked the fluid and it reads full. I am 95% sure there is not enough fluid in the trans. I have 4 questions.

1) is it absolutely nesecary to pre fill the TC before install?

B) is there any way to make sure the fluid is getting where it needs to go w/o dropping the trans again?

3) Would a power flush add fluid to the system and ensure there is enough fluid in the trans?

G) Do I have to drop the trans and fill the TC?

I think it is kind of obvious that I have never delt with auto trans b4, have swapped a few manuals tho. Also after about 30-60 min of driving around the trans temp climbs into the 200-220 range. It is a gradual rise in temp, it doesnt jump up. Thanks in advance

as per #1 it is a good idea to dump in a liter of oil but it is not possible to pre fill it as the pump will fill it, that is why the oil level drops when you start it up the first time and that should cover item B and G and if your driving it and the fluid level is full that makes item 3 a moot issue

if your driving around low three quarts something is odd as you would most likely have driving issues warm it up and recheck it and make sure you didnt overfill it
