Systems and methods for in-situ monitoring of gearbox are provided. An example system includes a mounting plate coupled to a component within the gearbox and a transducer array having a plurality of piezoelectric transducers disposed thereon to ultrasonically obtain diagnostic information about one or more components in the gearbox. The plurality of piezoelectric transducers are in contact with a surface of one or more mechanical components within the gearbox. The system includes circuitry, at least a portion of which is mounted inside the gearbox, electrically couplable to the transducer array, the circuitry configured to direct an excitation signal to a selected piezoelectric transducer of the plurality of piezoelectric transducers, and direct a response received from one or more of the plurality of piezoelectric transducers in proximity to the selected piezoelectric transducer toward a processor programmed or configured to determine gearbox diagnostic information therefrom.
