John Deere

The John Deere AT346370 is a genuine OEM transmission wiring harness engineered explicitly for heavy-duty powertrain control in John Deere crawler dozers. This professional-grade electrical cable assembly forms the critical communications network that links the main transmission controllers to vital hydraulic solenoids, electronic speed sensors, and temperature monitors inside the vehicle chassis. Built with high-grade, heat-stabilized braided protective sheathing, the AT346370 is configured to safeguard internal signal wires from aggressive mechanical abrasion, hydraulic oil saturation, and intense engine bay thermal cycles. Weighing 3.45 lbs and packaged inside a 12-inch structural height configuration, it features factory-molded automotive-grade connectors with weather-proof silicone seals to maintain low resistance and stop oxidation in wet field conditions. Utilizing an authentic John Deere factory wiring harness eliminates intermittent shifting faults, ensures correct voltage routing, and prevents electrical diagnostic failures across rugged earthmoving operations.
