Never: sealed Toyota Lexus transmission oil check with infrared thermometer - why you should not.

Never use infrared thermometer when measuring oil level on Toyota or Lexus with sealed transmission without dipstick.
Instead, there is a factory built-in "Fluid Temperature Detection Mode" that is a lot more accurate and easier to use and it doesn't require any expensive diagnostic tools or subscriptions.

Yes, simply put the procedure is based upon the temp reading from the sensor reading the temp of the fluid in the trans

Exactly

It’s odd how my Land Rover Freelander 2 with an Aisin TF-81SC the level is set at 60degC (140degF). Essentially the volume of ATF drained would be more, however, not sure of the expansion of the ATF WS.

You never made a video on how to enter transmission temperature mode.

It looked accurate to me...
The highest temperature is 126.5 at 1 minute 52 seconds in the video.
Two thermometers are always better than one.

The problem is that temperature range is too wide. When your required range need to be within 10 degrees & your margin of error is 10 degrees, its like up to 100% inaccuracy.
