Hi Opusnbill,I"ve wondered the same thing. I know the TSB shouldn't apply, as I have a 2021 made in February (so you would have to think the factory calibrations would be up to date).
Mine only bucks and jerks when it's cold. Once the truck has been driven a few miles it's great. Really odd.
It should be up to date so TSB should not apply. Take it to the dealer for diagnostics to see if something needs to be reflashed. This should not be happening in my opinion.
Best,
