hi all 328 owners with 8 AT, does anybody have a clue as if to there's a "break in" period for the transmission when driving only in sport mode? i normally dnt use sport mode, but now that im running on 19s i tend to get on it alot for better shock absorbtion but the shifts feel out of wack. hopefully Im asking the ? right but it seems to me as if the gears take longer to shift when doing 40 n under in sport mode. I mean I know it tightens up the suspension a little and throttle response is improved but I hate cruising through an alley or 35 mph zone and it feels like I'm in 3d gear revving up to 3 rpm all the time. any how I was just wondering if someone else is experiencing this shift lag..
