Just did the flush on my 2017 v6 rs a couple of days ago and it seems to be o.k...but, i still have a "clunking"sound when the car down shifts between 3rd and first..anyone know what this is??,,and for the people who are having their dealership refuse to change the fluid because they can't replicate the issue go back a few post and print out the tsb 18-na-355 it states clearly that all that is needed is a customer complaint, they are not required to duplicate the problem. I'm from canada and the fluid part # up here is 19418066, does anyone know if this is the same mobile 1 fluid they are using in the U.S. ?
