The information is being taken out of context. If the transmission was a "quart" overfilled, at what point was it being measured? What temperature? Was the engine running and the car leveled in park when you measured this added quart?
From the GM Performance instructions specific to the ZLE A10 transmission the side plug is the defining level of an A10 fluid capacity when the vehicle is perfectly level, idling in gear after the gear selector has made a pass from Park, reverse to drive and then idling. Using this method negates the model year pan specific stand pipe as it gives the proper level every time. The stand-pipe method is simply there to allow GM Technicians a faster way to fluid check/fill the transmission and not get burned by hot Cats in close proximity to the actual fill plug.
With 37,000 total miles, 14,630 miles on track using this method and the Amsoil Fuel Efficient "Blue Cap" ATF with zero issues with my ZLE, I'm going to go with user error on jack stands as my goto on why "an extra quart" is being questioned.
See the attached GM documents pertaining specifically to the A10 "Supermatic" used in the ZLE applications.
Hope this clears the misunderstandings.
