    Well i took the computer to a guy last week and had him tune it to my gears and get rid of the stuff i dont need, didnt get to drive it until today and it is still doing the same thing, What else could it be, ive already smoked one tranny and i dont wanna do that again, but the other tranny was doing the same thing so i wouldnt think it would be the tranny. Thanks
