Well it sounds like you may be having the same problem or beginning of the same problem i have. While i know there could be hundreds of differences its still not running right. I would if i were you get it checked out first before you do anything, just to make sure. Even do a fluid flush and filter replacement. This may do nothing but if it fixed it, it would save you lots of money. I did not have my transmission rebuilt. After dealing with 2 AAMCO shops i didnt trust them and heard that rebuilding at times can not be that good. So i went with a remanufactured transmission from Jasper. I heard and read that they were the best for that. It cost me about $2400 dollars for reman. and install. It comes with a 3 year 75000 mile warrenty, so i figured you cant beat that. Hope all this helps, and good luck.
