The 2016 Cadillac CT6 came standard with an automatic 8 speed automatic transmission. This transmission is known to have a major issue with shaking and shuddering. You're going to notice this more when you're on the highway and start accelerating. This issue can be very annoying but it doesn't mean that your transmission is in danger of failing or needing major repair. There was no recall ever issued for this. If your transmission is struggling to shift then it's possible you are low on transmission fluid. You should use the dipstick to check if it is low or if it needs a refill.
