If the fluid is between 105-115*F when you installed the plug. You are fine. If you removed the hex head bolt, that would be the drain plug. I have to ask, are you sure the plastic level straw is still installed?
If you drained the transmission with the engine off, its fine, but you will get more fluid out than what would normally be in the pan with the engine running. Its better to overfill by a Qt before setting the level than to be a Qt short.

Yes, you correctly described what i did. I'm not sure what the plastic level straw is (edit: i see via the diagram it's attached to the level check inlet drain hole)? I did drain the pan with the engine off. Checked the level with the engine on. Temps were between 100-105. My OBD reader has an ATF temp 1 & 2. 1 is generally 4-10% lower than 2.
I'm changing the oil in 500 miles. i'll recheck the trans level then and monitor the temps in the mean time. Haven't gotten above 150F yet, but it's ass cold too.
Is the trans temp the sure fire way to know if you are under-filled with ATF (besides the level check drain...let's assume the drain straw is dislodged).
