First off, new guy here, great site. I have an '08 G35x auto that I bought new. When I'm in stop 'n go traffic I experience what feels like the car bucking or shuddering when I first begin to move. The warmer the car is and the longer in traffic, the worse it seems to be. The faster I go or once I'm moving it goes away. It almost feels like I can feel the drive shaft spinning. I did a search and found a TSB but it only seems to affect 06-07 cars. Any help or ideas would be great because the car is going into the dealer Friday and I don't want them to think I'm nuts.
