I just completed a fluid change, filter change, and new PPE transmission fluid pan. (details in another post). My fluid level was between 1 1/4 and 1 1/2 quarts low from the factory! No leaks, and it has never been touched before. I have had one total clunky shift from 4-5 Right after the cam phaser software update. Other than that, I would say this transmission has performed flawlessly, except for high temperatures when towing. I am sure being over a quart low on fluid was not helping the temperature situation. I am hoping the updated thermostat, the aluminum transmission pan, and putting in the proper amount of fluid will help reduce the temperature.
