What does code P275C mean?

Q: What does code P275C mean?

Transmission Fluid Temperature Sensor D Circuit Low. P275C indicates that the transmission control module has detected an abnormally low voltage signal on the circuit for transmission fluid temperature sensor D, which is one of several temperature sensors used to monitor fluid conditions. The computer expects the sensor's signal to stay within a specific voltage range, and a low reading tells it that the circuit is likely shorted to ground or that the sensor's internal resistance has dropped.
