## Discrepancy

UPON DEPARTING, THE TRANSMISSION CHIP LIGHT ILLUMINATED.  PILOT LANDED & CALLED MAINTENANCE TECHNICIAN.  A VERY SMALL SLIVER WAS FOUND ON THE TRANSMISSION TOP PLUG.  THE LOWER PLUG WAS CLEAN & THE FREEWHEELING UNIT PLUG WAS CLEAN.  CLEANED THE TOP CHIP PLUG & REINSTALLED.  PERFORMED GND RUN & RETURNED TO SERVICE.
