Well he is the story. I got in my car to day and i am doing about 50 and i get on it a little to make it down shift. now it does but is just does not sound right. well i get to school and go to class. going back to work i stomp on it at a light. it starts to go but it feel wierd. the rps shoot up but no speed. well once i start going its fine. i had the tranny rebuilt about 1 year ago and put about 5000 miles on it. you think its junked

I doubt its the trans, it sounds like something with maybe the ICM, or a sensor issue; like it's not letting the car accelerate enough.
