Reply To: 2023 Gmc Canyon Transmission harsh downshift in the morning

I have a 2024 AT4X with the EXACT same issue. When the temp is <40 F, usually during first drive of the day, when I come to a stop or slow to approximately 8mph, the transmission will downshift harshly into 2nd gear. It is so abrupt that it feels like it will tear the driveshaft out. Are any other 2024 AT4X owners having the same issue? Please speak up!
