Took my 2018 ECODiesel into the dealer yesterday for an oil change and look at a couple of issues. (water leak, slow oil loss)
In closing out my bill the Dealer said there was a Witech update for my VIN, reporting it was a TCM update.
Since then I have noticed the transmission is not as sluggish, and am seeing about 3 MPG better fuel mileage. (24 hours isn't a full test, but my MPG is over 25, typically it is 22-23 and I am driving the same on the same routes)
