Also, on 2017's there is a software update for the TCM. It will help with the 1-2 hard shift on a cold start and drive. It will also correct a software error that can cause a random CEL. This is typically a free update at a dealership.

^^^ that software update is important, my 2018 already had newer software and never exhibited this hard 1-2 shift problem, even before it was tuned.
As TP2SS says, whether
a flush and a filter is enough depends on how long the trans was used after the shudder began, if the TCC clutch is worn too far, unfortunately OP's wife will need a new torque converter as well (loved the quick language lesson, too
). Let's hope the flush will be sufficient.
