Hi everyone, I have a 2019 3.0t with a little over 21k purchased just over a month ago. I've been experiencing the transmission kick up the rpms when I slow down from any speed above 20mph. It does it in standard and sport mode so it doesn't seem to be a drive mode issue. Not sure if this is normal or if something else is going on, please help!! There are no mods on the car besides an axle-back but I don't think the difference in back pressure has anything to do with this issue but I could be wrong and the brake booster had to be replaced recently.
