My transmission didn't take nearly 1,000 miles to smooth out. After like 250-300 miles it was smooth as silk.

I wonder how much of this is due to the dog clutch design. Traditional automatics shifted soft at low speeds by delaying the clutch engagements (as well as the cushioning effects of the torque converter). Dog clutches are far more efficient and probably more durable, but it's not easy to make them shift softly. Additionally the MPG requirements are forcing them to keep the TC locked until just the moment of shift, then lock again right away.

I suppose that a lot of this could be changed through timing tweaks and hopefully the adaptive system will help. But it still beats CVTs. And it will never be a Dynaflow.

I just posted a similar comment/question in another thread. Glad to know I'm not the only one... though I've got just over 3,000 miles on mine now and still experiencing the rough shifting out of my driveway. Would the dealer have record of weather or not it was "re-flashed" as someone mentioned above?
