Hi i own a 2004 honda accord v6 auto transmission. i had a rebuild tranny and transmission done from my step dad shop. But the problem is after the rebuild its running different, first it shakes my car inside feels as if im getting a massage vibrate, but the main problem is my car some times doesnt want to go. I would start my car , let it warm up and once i put the car into D (drive) and push onto the gas pedal it wouldnt go, the RMP would rumb up to 10-40mph and car still would not go. until I put my car into 1 it will take off, than i have to auto shift to 2, and than D3 and than D for the car to run normal. Whats WRONG?help!
