I have a drone from the transmission at 1500 rpm and under a slight load (4 & 5 gears. When I change to manual mode it goes away. Shifts just fine otherwise. Chrysler will not fix the noise so I have contacted a lawyer to help resolve this issue. By the way I drove a 2010 R/T and it had the same noise.
Love everything about the car except the noise from the transmission.
