## Discrepancy

UPON TAXING OUT, THE TRANSMISSION CHIP LIGHT ILLUMINATED.  THE PILOT RETURNED TO THE PAD AND LANDED AS SOON AS POSSIBLE.  ON SHUT DOWN WHILE TURNING OFF FUEL BOOST PUMP CIRCUIT BREAKER SWITCHES, THE LEFT TRANSFER PUMP LIGHT DID NOT ILLUMINATE.  THE MECHANIC REMOVED AND REPLACED LT FUEL TRANSFER PRESSURE SWITCH ALSO THE MECHANIC FOUND A SMALL METAL PARTICLE ON LOWER TRANS CHIP PLUG, HE CLEANED THE PLUG, REMOVED AND REPLACED TRANS OIL AND FILTER, COMPLIED WITH PENALTY RUN AND THE AIRCRAFT WAS RETURNED TO SERVICE.
