I put the vehicle up and it sat overnight so I could get started in the morning. First, I checked the fill plug as the videos recommend, then I pulled the check plug - fluid poured out. I didn't get to measure it, but probably around a quart minimum. Then I pulled the drain plug and moved along as expected.
I pumped fluid into the transmission, about 3.5 quarts. I have not warmed up the vehicle to "check the level" yet. But I know I am over the check standpipe.
Has anyone else pulled the check plug on a new transmission and had fluid pour out? Do you need to have the engine running when checking the fluid while hot?
Thanks,

You only really pull the Check Plug when the engine is running with the transmission in Park. The fluid level will be "higher" with the engine off because the fluid sits in the pan, you're checking the fluid level with the system operating (fluid circulating) which will drop the level in the pan to the just at the Check Plug Tube (if it's set correctly).
To correctly check the fluid level, the vehicle needs to be on relatively level ground, the transmission needs to be warmed up to between 104°~113°F, this can be checked with a scantool capable of reading the Data List item "A/T Oil Temperature 1," you can also use the "Check Mode" method that uses the instrument panel to indicate when the transmission is at temperature, an additional (technically less reliable, but due to the tolerance range of the specification you should be fine) method is using an IR Thermometer to monitor transmission pan temperature. I would add a +/-2 to 4°F variance to your measurement given the temperature outside and how long the vehicle has been running
IF you go this route as while the temperature sensor is located in the valve body, there will be a little bit of variance as you're measuring the fluid through a steel layer that can vary a little.
In general I like to shoot for the middle of the specification, so in your case about 108°F or so as that gives a good margin for error. I'll attach the PDF for the procedure for flushing your A750E transmission, 3.5qts of WS ATF or "approved" (it's a bit of an on-going debate, but check the forums for fluids that members have tried and haven't had issues with) equivalent fluid for drain and filling the pan sounds about right, you should be well over the check tube with the engine running with that amount, so maybe when you hit about 100°F I'd pull the check plug and let it drain until you reach specified temperature. I would do at least two drain and fills to a good flush going (if you're doing multiple flushes, you don't need to set temperature until you're at your last drain and fill, just run it about 10-20 seconds or so while shifting through gears to get it to push fluid through all the passages); you don't need to drain every last drop out, you're looking to get the majority of bad fluid out and new fluid with new additive package in.
Hope that helps.
