131-2150 1312150 Transmission Wiring Harness for 980G Wheel Loader

The primary function of the transmission harness is to facilitate the monitoring and electronic control of the transmission, enabling the smooth, efficient, and safe operation of the machine. Its key roles include:

Sensor Data Acquisition: The harness connects various sensors on the transmission to the controlling ECM (typically the Transmission ECM). These sensors provide real-time data, such as:
Speed Sensors: Input and output shaft speeds, turbine speed. This data is crucial for determining shift points, slip detection, and overall transmission performance.
Temperature Sensor: Monitors transmission oil temperature. The ECM may derate power or modify shift patterns if the temperature is too high to prevent damage.
Pressure Sensors: Monitor clutch actuation pressure within the transmission.
