Looking to get some insight into why a 2023 GMC Sierra 1500 8-speed SLE 2.7L L4 would shudder when accelerating around 80-100 km/h (50mph to 62mph) between 2000-3000RPM. It began doing this last winter, and hasn't been used since, but it continues to have this issue. I used to be able to sustain the shudder for longer, but now it only lasts about 2 seconds.

Those are your ONLY options at GMC, Chevrolet and Buick - well, depends on what you define as SUV or CUV.
The Traverse is essentially a minivan wearing an SUV costume, lower roofline, higher floor, upright grille and flat hood. Looks like a Tahoe performs like an Impala.
There is a new software security system/encryption on the '24 and up GM diesels and as far as I know, not even the Canadians nor eastern bloc hackers have jailbroke these ECMs. Hence, you can look hard but there are no delete kits for a '24 GMC/Chev Duramax. '23 L5P, yes, '24, nope.
My '24 has had no ATS issues in 60k miles, knock on wood.
Wow, this thread is still going.
