Overview
The ZF 6073.015.119 EST 37 A for WG210 is a critical electro-hydraulic solenoid valve assembly designed to modulate clutch pressure within the WG 210 series transmission. This OEM genuine part, identified by SKU 6073.015.119, sits directly on the valve body and translates electronic control signals into precise hydraulic actuation. It governs shift timing and torque converter lock-up, ensuring smooth gear transitions under heavy load. When paired with the 4657101080: TRANSMISSION HOUSING, this component forms the core of the transmission’s shift logic. The EST 37 A variant is engineered for high-cycle industrial applications, offering enhanced resistance to thermal degradation compared to standard solenoids.
Symptoms of Failure
- Erratic shift hunting or delayed engagement: A failing 6073.015.119 often causes the transmission to hunt between gears or hesitate before engaging, especially during cold starts. This is a common search query for “ZF WG210 shift delay fix.”
- Torque converter shudder under load: Worn internal seals in the solenoid lead to pressure bleed, producing a vibration or shudder when the converter locks up at highway speeds. This symptom is frequently searched as “ZF 6073.015.119 shudder.”
- Intermittent limp mode with diagnostic code P0741: The valve’s inability to maintain line pressure triggers fault codes related to clutch slip. Operators often search for “WG210 limp mode solenoid replacement.”
- External oil seepage at the valve body interface: Degraded O-rings around the solenoid body cause visible fluid leaks, often mistaken for housing cracks. This aligns with long-tail queries like “ZF transmission solenoid leak WG200.”

Compatibility
This solenoid is primarily designed for the ZF WG210 series, but it also cross-fits select models in the WG180, WG200, and WG211 families where the valve body architecture is shared. It is not compatible with the older WG120 series without adapter plates. For proper installation, ensure the 4657201167: HOUS.FRONT SECT and 4657201171: HOUSING REAR PART are free of debris. In WG200 applications, the 4657298103: HOUSING REAR SECTION must be torqued to spec to prevent cross-threading the solenoid bore. Always verify the valve body casting number before ordering.
