all it does is affect shift points...almost redline at W.O.T. / like 3200 at %50 throttle. Didn't know it affected downshifts....but then, I've never not had the button down.

I guess the net effect is to make downshift easier since the shift points are set differently. All I know is that when pulling a steep hill with the button off, I had to floor it to get it to downshift. With the button on, much less accelerator pressure to downshift. Of course I could have manually downshifted but didn't think of that at the time.
