I used a Non Contact thermometer pointed it at the pan in several locations to get this temp. or if you have device that plugs in the OBD II port and interfaces with the trans ECU and uses the trans temp probe to measure fluid temp. I waited until oil temp was at the upper part of temp scale that is written on the pan then I removed the fill plug and let the excess oil drain out until it was dripping slowly out the fill plug. Then reinstall plug & torque.Take the car for a test drive and warm up trans to operating temps. then check for leaks and if none found you should good to go!!
Tip: make sure the engine is running for the final check on the fill plug.

Story: I just changed my ATF in my 92k mile wagon with Valvoline Synthetic from Amazon ($40 for 6 quarts). I had 5.5 quarts come out, but could only put 4 back in, which made me pretty concerned about driving it. I didn't understand that the transmission would pull fluid in while running. But after reading a ton of posts, and watching some youtube videos, I realized that the engine must be running during for the final check. When I did this, another 1.5 quarts went in! Much smoother shifting now, and no gargling sound. Thanks everyone!
