You've given some excellent advice. I'll just add a few more observations: there is a single "shift" that occurs somewhere in the 10-20 MPH range, depending on how hard you're accelerating (if you're accelerating slowly then it's around 10 MPH). I was under the impression that this is like a true first-gear that hands off to the CVT, but I don't know for certain.
Just FYI, the CVT doesnt ever shift. what you percive as a "shift" is actualy just something programed into the trannys programing to make people think its shifting.... Same thing with the autostick, all you are doing is forcing the tranny into a lower or higher "gear", but its not really a gear, its just a different ratio. CVT's dont have gears like a normal auto tranny, inside your CVT you will find, basicaly, two pullys connected by a metal belt. the "gear" ratio is controlled by, basicaly, varying the size of the pullys....
So why the fake shift?
When the first generation of CVT's came out, people wouldnt accept them, they kept bringing them in thinking something was wrong, becuase it was "stuck in gear".... Of course being used to a normal automatic, when you are accelerating and the engine revs high and stays there, it IS stuck in gear, right? But of course, thats normal operating procedure for a CVT....... So by programing in a fake shift at about the point where a "normal" auto does its first to second shift, they have tricked people into accepting it, and saved a whole lot of uneeded "service" calls......
You will notice is you accelerate full throttle, you dont get that "shift", because in reality, it slows things down, so when you are asking the tranny to give you all its got, it forgoes the fake shift and just revs up and goes....
