When going downhill and compression braking, the first three will go to D when the speed stabilizes, three will hold in the paddled gear.
What's up with that?
My feeling is that they all behave the same. There's probably several variables in play (such as incline, speed, rpm..etc) to determine when it switches back to D.
Side note, I turned off auto climate control today and it seems to improve my fuel economy by ~9%. More testing to come.
