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?

Why is this not a "check transmission" light ?

Hopefully the tranny is ok. Apparently an computer issue? We'll find out.

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.

Looks like you boys are right on, looks like a multi pin connector not fully seated. 👍

Dealer, they had to check the code and then track it down.
