2019 XLT- love this tranny compared to 2013 Yukon 6-speed. One time when punching it to pass I got a nanosecond stall, yet the Yukon would always hang in a higher gear before downshifting.
And the engine grade braking is awesome; I bet not too many know you can really slow down on cruise while pushing the down button.
