So I got my X last November('05 AT) And in the past few months i've started to notice a few things. The first thing is that upshifting to 1st is such a rough transition. It will jump instead of shifting smoothly. Kinda hard to describe. The second thing is that whenever I drive on the highway( or highway speeds) periodically it will feel like I am on rumble strips for maybe 3 seconds. I know exactly where it is coming from( I think) and that is the tranny. It stopps whenever I take my foot off the gas. Help?
