2020 GMC Yukon transmission failed at 103.000 miles

The transmission is out. Prior to it going out, I experienced loss of power, gear slipping, shuttering and not being able to go among other things. This is very dangerous and can cause serious accidents to occur. This should not be happening on such an expensive and newer vehicle.

Less than 4 years old and I am having…
