## Discrepancy

FLIGHT 3778 NOTICED A/C WAS LOSING OIL PRESSURE IN THE NR 1 ENGINE DURING CLIMB AT 1000 FEET.  CREW SHUTDOWN THAT ENGINE AND DECLARED AN EMERGENCY AND DIVERTED TO ROCHESTER.  FLIGHT WAS HEADING FROM BUFFALO TO LGA.  FLIGHT LANDED WITHOUT INCIDENT.  MAINTENANCE SWAPPED NR 1 AND NR 2 OIL PRESSURE INDICATORS AND TRANSMITTERS FOR TROUBLESHOOTING PURPOSES, THEN REPLACED THE AFFECTED NR 1 OIL PRESSURE TRANSMITTER.  ALL OPERATIONAL CHECKS AND LEAK CHECKS WERE GOOD.  AIRCRAFT RETURNED TO SERVICE.
