This transmission temperature sensor monitors the thermal state of the drivetrain fluid. It sends a signal to the machine’s control system, which uses the data to alert the operator or adjust operating parameters when the fluid temperature exceeds a safe threshold. A failed or inaccurate sensor can prevent the system from detecting overheating, which risks accelerated wear of gears, clutches, and bearings in the transmission. As an original AGCO component, the sensor’s electrical resistance curve matches the calibration of the host tractor’s instrumentation, ensuring the temperature reading corresponds to the actual fluid condition. When replacing the sensor, verify that the electrical connector is clean and fully seated to avoid intermittent signals.
