Nitro4, Alot of people say that's a problem only the 04's experience. I have to admit, I drove an 05' a couple of months ago, and it did shift smoother than my 04' does.
I've got 20k on mine, and I think it shifts better now than it did when it was new, and it always seems to shift better after it warms up.
As you pointed out, it's only the 1-2 shift that seems to have any "issues".
Mine is just a little "notchy", but I'm use to the way my Hondas shift, and of course there's no comparison.
