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.

Wow, I don't think they ever did the software update on my 2017. I had to get the triple flush twice. I still have the hard 1-2 shift.
