P0700-transmission Control System (mil Request)

This is the PCM code that indicates you have codes stored in the TCM (transmission control module).


It could have been a loose power connection to the TCM triggered some codes and then you got the PCM code but I would ask for some clarification on the whole "it was a loose battery terminal" thing and make sure they didn't just clear the codes for S121.22.
