Default C8 trouble code: Lost communication with transmission

Hi all,
Got a check engine light today. Tranny was not engaging and there was a code for Lost Communication with transmission. Anyone else see this?

Hopefully, something as simple as a loose connector.

Agreed. Just hoping the Dealers have some good backup from the factory. New ballgame for the Techs.
