think my trans is going
 

160k on the trans (Auto) and for a while (8 months) the car under normal acceleration hesitates like its going to shift to a higher gear then finally would but it wouldn't do that all the time. didnt think to much of it as i dont beat on the car that much and really just DD with it. last couple of days the car has felt completely sluggish and has no pep at all, nothing. I just leave it in drive but i wanted to see if i actually put it in first or second if that would change things and the car wont move when i put it into 1st. i have to give it a ton of gas and it will move forward then stop as soon as i let off.

trany problem right? prob time to rebuild or the stall is shot.

sounds like the trans
