I have a 2020 GMC 2500. I don't have drips on the ground yet, but I do have a trans fluid on the inspection plate at the bottom of the bell housing. I have about 10k miles. Fluid level is still good, but will take it in soon.
 
Same place mine is coming out of, but maybe not quite as bad as yours. I only get one small bubble on the middle of the inspection plate. when I pull the plate off and poke around inside with my finger, it feels dry. Did you see any oil spray on any of the undercarriage?
 
I finally made the mistake of bringing my truck in to get the leak fixed. They had it for about 3 weeks and did the TSB for the leak. Had it home for a week (the truck isn't used during the week). Used once and the leak came back worse than before. Took it right back. Now it's been about over 4 months in total the truck has sat at the dealer, now waiting on a torque converter that's on backorder. They think it will be at least another month. Tried to trade it in at the dealer on a different truck, they didn't even want it because they have no idea when they would be able to sell it.

Last week my wifes new 22 suburban z71 had a total brake system failure at less than 5k miles. Almost caused a serious accident, when she had about 20% brakes trying to stop before a busy intersection. It's stuck at the dealer waiting on a backordered master cylinder and brake booster. I'm done with GM.
