213-2213 2132213 Transmission Wiring Harness for 980G Wheel Loader

Solenoid Actuation: The harness delivers power and control signals from the ECM to the solenoid valves located on the transmission valve body. These solenoids are electro-hydraulic valves that direct oil flow to engage and disengage specific clutches, thereby controlling gear selection and shift quality.

Power and Ground: It provides a stable and clean power supply from the machine's electrical system to the sensors and solenoids. It also provides a dedicated ground path, which is essential for accurate sensor readings and reliable solenoid operation.

Data Communication: The harness integrates with the machine's CAN (Controller Area Network) data link. This allows the Transmission ECM to communicate with other modules, such as the Engine ECM and the main machine monitoring system (like CAT VIMS). This communication is vital for coordinated functions like engine derating during a shift or transmitting diagnostic codes.
