Years ago GM was having an issue with a transmission fluid leak out of the bell housing. After several repairs and sending every possible seal in to GM that could possibly leak, they figured out that when they cut the notch in the torque converter it left a sharp edge that was slightly cutting the seal upon installation of the converter. Wasn't a big leak, just dripped a couple drops after each drive cycle. Not always as simple as it seems.
Checked both my 2020 and 2023, no leaks. If you stick with a decent dealership, hopefully they'll keep track of what they've done as it goes on until its repaired. Don't get discouraged. Its just an axle seal leak. Overall, they're awesome trucks.
