95 4.6, basically all stock. I have the AOD tranny. When at a set cruising speed, car will occasionally shimmy (feels like a straight drive does when you're geared too high on a dirt road, lol). Also, if I take off from a stop like I have some sense, car will not shift right, it'll just rev the engine up really high and not shift up (this is only a sometimes problem too, since I rarely take off slowly). I'm thinking that it'll soon be time for a rebuild, any thoughts?
