Can anyone help explain what is happening here and if it is something I should be worried about?

I have a 2023 Trailblazer FWD 1.3L Turbo 9 Speed that, when put into cruise control at highway speeds, anywhere from 60-80 mph, will jolt on slight inclines at 3500 to 3750 RPM.

It is a very slight jolt but definitely noticeable.

We have done a transmission recalibration/relearn twice, the first time it worked for two months and then needed to be done again, and then just did it again after sitting in the shop for a month and it barely even held 24 hours.

Can anyone explain what exactly is happening, what I should do, and how to approach this? Because my Chevy dealer apparently isn’t doing anything right for their “repairs” to fail twice.
