Usually when I am slowing down, the motor is winding down and you feel it in the tranny BUT when it gets to 40mph the tranny vibrates rought. It starts off smooth and then does it. Plus, i have been hearing some weird sounds. I back up the other day and it sounds like my tranny was just dangling What do you guys think?

It was doin that since I got it at 2000 miles. It hasn't gotten any better or worse...but you still got warranty on it.

 

Yea, I read that a while back. I'm going to take it to the dealer just to be on the safe side.
