I found this thread, luckily, and wanted to report my symptoms and outcome with my 2013 CTT with the GIAC tune and the Tubi exhaust. The car was originally from Florida (reads hot temps) and the TC had been replaced at 45k.

The car would make a clunking sound on slow, sharp left turns...initially, and then developed a strange stutter in 3rd and 4th gears. The acceleration did NOT feel smooth at all. I decided to go with the fluid to see if it would solve my issue. Bingo! I have only done a single change and one short test drive, but it feels night and day. My old fluid was very black!

deilenberger, I pulled the last table update and wanted to add my success to the list! Thanks to all for this thread!
