ok just bought an 07 g35x with 49k miles. when u take off easy it goes from first to second fine then while in second it feels like the trasnny skips for a second, rpms drop maybe 100 or 200 then shifts to third. also while going down hill coasting almost feel like car is being held back. this is my second g, my previous was an 05 and the tranny felt much smoother on that car this one. my next question is the 6 year 70k powertrain warranty transferrable from first owner to next.thankyou
