Transmission Holding Lower Gear After Moderate to Hard Acceleration

My 21 Suburban will do that but I put it in sport mode quite often. I like how the suspension stiffens and the shift points are a little more aggressive.

I've observed this behavior on other 8 / 10 speeds in Sport mode.... will need to pay more attention (if and when I ever drive our 2024!) if this happens in normal mode on the GM 10 speed.

The suspension stiffens? @jerry455 I could be wrong but I’m not aware of our vehicles having adaptive suspensions in sport mode. I have an 24’ AT4 XL with air ride suspension and never heard of this.
