I have the following (directed) graph:
A --> B
the transition is labled C. Is there symbol to denote the inverse of the (A,B) transtion?

As Yuval mentioned there's no direct simple standard notation. But:
a directed graph is a relation, and this an be represented by a square adjacency matrix $A$, so the graph with all edges reversed has the transposed adjacency matrix $A^T$.
in category theory, for a given category $C$, the same objects and the reverse of all arrows as $C$ is called $C^{op}$.
