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)

Does your receipt say anything about it? Part or version number?

I looked, did not see any details, all that is listed is WiTech Update.
It greatly reduces the cold shift lag, and appears to go to 8th gear quicker on the road.
