under warranty still? if so you may have a chance to put it back to stock and see if they will take care of it.

It is caused by a bad torque converter solenoid. Clear it and see if it comes back. Also, reload a tune.

Converter solenoid is probably bad or has trash in it. This is actually the first time I have ever seen this code.

Yea, my buddy and I were saying the same thing, never heard of anyone throwing this code. I picked up the solenoid yesterday, is it just as simple and dropping the pan or does the whole thing need to be opened?
