I was wondering if this happens to anyone else with a 2.5L, does the car shift hard through the gears cause mine does if im not exactly at about 3 grand. And also this happens a lot from a stop, if i want to go easy on the gas it would just down shift on its own real rough and it just pisses me off cause i like a smooth ride and i dont always want to gas it a lot from a stop cause i want to conserve gas sometimes. just hit me back cause i dont know if it a trany problem cause i heard that the trannies on the millenias are not that great. well hit me back anyone if they have that same problem or if they know anything about this problem.
