The P073C fault code indicates that the transmission is stuck in a specific gear. The Transmission Control Module (TCM) is responsible for monitoring the transmission gear and setting the OBDII code when the actual gear does not match the gear commanded by the TCM.

This fault code suggests that there is an issue with the transmission system, causing it to remain in a single gear instead of shifting as required.

It is important to address this issue promptly to ensure proper functioning of the transmission and avoid potential damage.
