Hi, recently bought an 05 4.0 V6 5 speed. Test drove and it seemed fine. Now that I have driven it more, I can hear a light rotational noise that increases with speed and is most noticable when engine is under load. When I touch the lower part of the shifter I can feel a vibration and it seems like that is where the noise is coming from. It is not really very loud but I am wondering if these gearboxes are noisey or have I got problems? Thanks, Jay
