Hi all,
I have a SRT roadster and wondering f anyone else experinced this, or know what it is.
Vehicle has about 12k miles on it.

Under certain conditions as below:
-Shift from 1st to 2nd
-Downshift from 2nd to 1st
Shifting described above is when trans is in "D," not manual selection. I have been trying my best to isolate this sound to figure out what it is.

Under the mentioned conditions, I sometimes hear a sort of metal grind sound. Best way I can describe is that it sounds like a bearing wearing out, and occurs right at the shirt point for maybe 1/2 a second and goes away. The noise is more prevalent if engine under considerable load.

Thanks in advance for your help!
