Sparky

I'm looking for info regarding how the auto tranny in the new Altimas perform with the 3.5 engine. I know, I know, autos are for wimps, but it's about convenience (with two kids and all). I've had a few decent cars with sticks (Acura Integra GS-R), but am looking into a performance sedan and like what I see so far in the Altima. So, does the auto behave well or what (shift points, etc.) and are there any aftermarket goodies for it?

Thanks all.
