The issue is in the Torque Converter. Mine had the "shudder" issue at 2000 miles and was flushed and reprogrammed. I think the issue is just coming back in another form. Pretty sure they are going to replace the converter, valve body, or whole thing since I had the shudder issue prior. My service adviser is already prepared to clear out a bay and reserve his transmission guy for Monday when I bring it in.

The car also used to shift a lot firmer at moderate to full throttle. Now only 1-2 shift has a good kick and the rest, while quick, feel sloppy and loose.
