If he was more aggressive on the throttle then no noise. We tried running in Sport mode and no trans/clutch noise no matter how he drove or accelerated.
My summation is that Drive should really be Economy mode and only suitable for highway or freeway driving.
While I experienced some stutter when applying light throttle at low speed while in Drive, there was never any accompanying noise or grinding. That might worry me. I prefer driving about town in Sport mode because it can be smoother while accelerating (though less so decelerating) and seems to stay in the power band a bit better, but I have not experienced anything that I thought was unsafe or unusable about using "drive". If I was getting some kind of noise or grinding, I would head back to the dealer.
