Torque converter failed. Confirmed by dealer service department. No warning indicators. Dealer repaired under warranty but it took 3 months from the first phone call. Looking online at user boards this should be a recall issue. I was told I could continue to drive it until parts came in and only found out later that the transmission could be damaged by doing so.
