I've had my 2024 AT4X for a month and I've noticed the transmission shifting sucks. Unless I come to a complete stop, it won't downshift into 1st. I 've slowed to 1 mph (near-stop), then stepped on the gas it still wouldn't downshift to first. It would accelerate from 2nd. Also it shifts really hard when shifting from forward to reverse. It's not due to not completely stopping when changing directions as I'm religious about coming to a complete stop, Also the transmission shifts are annoyingly slow. GMC really needs to make this transmission performance match the engine performance.

The 2nd gear start if not stopped is normal.  The 8 speed has done that since 2015 when it came out.  No need for 1st gear ratio if its still moving as 2nd gear is still plenty tall.  

 

As for shifting speeds, try a different drive mode and see if it helps.
