ZF 6073.017.055 TCU ERGOPOWER M/L EC4A for WG210 | OEM Genuine Part

Overview

The ZF 6073.017.055 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 system. Positioned on the valve body assembly, the TCU interprets input from vehicle sensors to optimize gear selection for heavy-duty applications. The SKU 6073.017.055 ensures precise compatibility with WG210 gearboxes, replacing worn or failed units to restore factory performance. When paired with a properly sealed HOUS.FRONT SECT (4657201161), this TCU maintains hydraulic integrity and prevents contamination from entering the control module.

Symptoms of Failure

• Erratic shifting or delayed engagement – The TCU fails to process speed sensor data, causing harsh or missed gear changes under load.
• Transmission stuck in limp mode – A faulty 6073.017.055 unit triggers error codes, forcing the gearbox to operate in a single gear for protection.
• Intermittent loss of communication – The ECU cannot read transmission parameters, leading to sudden power loss or unresponsive shift paddles.
• Oil temperature sensor faults – Degraded internal circuitry produces false high-temperature warnings, risking thermal damage to seals like the O-RING (0634313603).

Technical Specifications

Compatibility

This TCU is engineered for the ZF WG210 series, but it also fits select WG180 and WG200 variants when used with the correct 螺栓 (0636115293) fasteners. The EC4A logic is shared with WG211 and WG212 models produced after 2015. Always verify the transmission serial number before installation. For secure mounting, use the CYLINDRICAL PIN (0631306816) to align the TCU bracket precisely.
