Had the clutches and TCM flashed on my 2015 in Feb 2018 at 34k. Been acting up for a while, finally scheduled an appointment at 40k and they flashed the TCM again. The DCT is only slipping 50 rpm per the test, so no need to replace clutches again. Seems to shift better than last winter. So, was there a new version of the software, or did the TCM just forget something from the previous flash?
