2020 AT4 5.3L with possible tranny / Torque converter issues?

[ajs800]

I am approaching 15k miles on my '20 Sierra AT4 and over the last few thousand miles have noticed a slipping type feel while under load.  It may not be tranny related and more torque converter but between 60-75mph under soft load it tends to  jump and has a pretty noticeable slipping feel.  I know the 10spd is known to be solid (thus far) but any other common driveline issues with these trucks?  I never seem to have luck leaving it in dealers hands without guidance but I might be forced to at this point as I am not finding any common or well known problems when researching.
