ZF 6073.017.103 TCU ERGOPOWER M/L EC4A for WG210 | OEM Genuine Part

Overview

The ZF 6073.017.103 TCU ERGOPOWER M/L EC4A is a critical electronic control unit designed specifically for the WG210 series transmission. This OEM genuine part manages shift logic, clutch modulation, and diagnostic communication within the ERGOPOWER M/L EC4A system. Positioned as the brain of the transmission assembly, it interprets sensor data to optimize gear engagement and torque converter lockup. The SKU 6073.017.103 ensures precise compatibility with ZF’s heavy-duty drivetrain architecture, replacing worn units to restore factory-level performance. When installing this TCU, technicians often pair it with the 4657201161: HOUS.FRONT SECT to secure the control module housing, and the 0636115293: 螺栓 for mounting integrity.

Symptoms of Failure

• Erratic gear shifting or delayed engagement – The TCU fails to process speed signals, causing harsh or missed shifts under load.
• Transmission enters limp mode – A faulty 6073.017.103 triggers diagnostic trouble codes (DTCs), forcing the gearbox into a reduced power state.
• Intermittent loss of communication – The control unit may drop CAN bus signals, leading to sudden neutral or unresponsive throttle commands.
• Oil temperature sensor errors – Degraded internal circuitry misreads thermal data, potentially causing overheating or incorrect clutch pressure.

Technical Specifications

Compatibility

This TCU is engineered for the ZF WG210 series, but its ERGOPOWER M/L EC4A logic also supports select WG180, WG200, and WG250 variants when paired with the correct harness. Always verify the 0634313603: O-RING seal condition on the housing interface to prevent fluid ingress. For mechanical alignment, the 0631306816: CYLINDRICAL PIN ensures precise dowel placement during reassembly. Cross-reference your transmission serial number with ZF documentation to confirm fitment.
