While test driving the car, I heard a noise that I can only describe as a low, grinding noise (like grrrrrr) that is coming from somewhere in the drivetrain... it could be the differential or the transmission. I couldn't really determine the location of it. It's noticeable only during launch from 1st and most low speed.

When the car speeds up and I'm in 2nd+ gears, I don't hear it anymore or not audible enough. I have driven 350z's and I don't ever remember such a noise and I would suspect that 370z's are the same.

Can anymore confirm or explain what this noise may be? The dealer says their techs checked out the car and it's fine. It's a certified pre-owned car and still have warranty left for up to 35k+ miles or 3 years or so. Would such a warranty cover possible tranmission replacement?

Thanks!
