2011 sentra sr cvt noise

[11sentrasr]

I have a 11 sentra sr with the cvt transmision, the car has 56000 miles on it. When I put the car in drive and it is in "1st gear" it makes a noise like if your dragging somthing plastic under the car while accelerating. Although it does not happen in any other "gear." I can free rev it in neutral or park and it wont do it, only when it bearly gets going in 1st gear ratio. Any help would be much appreciated.

the cvt doesnt have an "gears" per say. put the car on jackstands, make sure the rear wheels are blocked and its secured with jackstands, have someone gently rev the engine with you underneath on a creeper. see if you can isolate the noise that way.
