Nothing has been taken out of context.
It's hard to believe your providing this level of misinformation when in your video, link provided below.
You're using a procedure as Quoted in your video for a street rod package.
"After scouring the internet for information about how to change the ZLE's A10 transmission fluid, I stumbled upon the installation instructions for the @GeneralMotors Performance Catalog installation instructions for the LT4/A10 street-rod crate package."
The overfill was measured using the exact procedure as recommended for the Zl1-1LE by GM with the engine running, the car perfectly level and the transmission fluid temp at 207 degrees F which is exactly in the middle of the recommended temp range with the fluid temperature between 203 degrees F and 212 degrees F as measured by the I Banks gauge from the CAN buss / factory sensor.
Although your car's transmission may not experience issues, mine came from your shop with the fluid overfilled by 1 quart after having the transmission fluid flushed and was shifting erratically on track.
After I checked and refilled the level per GM's procedure for the 1LE it has had no further shifting issue.
