I have a 2006 g35 auto sedan with 26k miles. When i accelerate from a stop the switch from second to third gear has like a double bump to it in the 3-4k rpm range. This is really hard to explain, its like a rough shift between the gears, its not too noticable but i notice very little things. Is this normal or could this be the sign that i will need a new tranny in the future.?? I dont want to go to the dealer either for such a small thing that some wouldnt notice? thanks
