Overview
The ZF 6041.222.158 ELECTRON.MODULE is a critical electronic control unit designed specifically for the WG100 and WG200 series transmissions. This OEM genuine part manages hydraulic valve actuation, shift timing, and diagnostic communication between the transmission and the vehicle’s electronic system. Positioned directly on the valve body assembly, the module interprets input signals to regulate clutch engagement and gear selection. The SKU 6041.222.158 is engineered to meet ZF’s exacting standards for durability in heavy-duty industrial applications, ensuring precise electronic modulation under high thermal and vibrational loads.
Symptoms of Failure
When the ZF 6041.222.158 ELECTRON.MODULE begins to degrade, operators often notice erratic shifting patterns or delayed gear engagement, especially during cold starts. A common long-tail search query is “transmission electronic module failure symptoms WG200,” which includes intermittent loss of communication with the ECU. Another frequent issue is the transmission entering a permanent limp-home mode, restricting speed to protect internal components. Additionally, corrosion on the module’s connector pins can cause intermittent power loss, leading to sudden neutral drops. If you observe any of these signs, inspect the module alongside the 4644105417: DISCONNECTION unit, as both share the same harness circuit.

Compatibility
This electronic module is engineered for ZF’s WG100 and WG200 series transmissions, including the WG180, WG200, and WG210 variants. It directly replaces units in off-highway vehicles, mobile cranes, and heavy-duty trucks equipped with these gearboxes. The module interfaces with the 4644303547: OUTPUT FLANGE and 4644303012: OUTPUT FLANGE through the transmission’s internal wiring loom. For complete assembly, ensure the 4644101121: TRANSMISSION HOUSING is free of debris before installation. Always verify the software version matches your transmission’s ECU calibration.
