im guessing they simply got their math wrong and also supply chain issues didn’t exist back then. GM might have thought fewer failures, and with that a ‘break in’ fluid change was not needed or was too expensive to include. As it stands, they figured out that contamination was an issue, so I’m sure they cleaned that up, but the tranny needs even cleaner assembly or initial clutch disc wear was too much. They know the answer, they aren’t stupid, but they won’t tell us, either way, I’m changing the filter asap, then again with a fluid flush and track fill. GM operates by counting pennies, luckily I don’t, I just want my stuff to work.
