Well, I've been trying to accelerate hard to see if it will do it again and it seems like it will if I push the accelerator down while it's doing it's shift. I'm not about to slam the accelerator down all the way or anything, just if I give it extra gas during the shift it goes up a lot. But say I am accelerating quick and I hold the gas pedal where it is; it shifts more normal. Which I guess makes sense anyway. Oh well, at least I have a warranty.. I hope
