## Discrepancy

THE NR 2 ENGINE SUDDENLY AUTO SHUTDOWN WHILE CLIMBING THROUGH 19K AFTER TAKEOFF FROM EWR.  THE AIRCRAFT WAS RETURNED TO EWR WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE TRANSFER GEARBOX AT FAULT.  THE NR 2 ENGINE TRANSFER GEARBOX WAS REMOVED AND REPLACED IAW MM 72-62-01.  LEAK AND OPERATIONAL CHECKS WERE GOOD.
