Overview
The ZF 6073.015.071 is a precision-engineered OEM genuine component specifically designed for the WG 190 series transmission. This part functions as a critical hydraulic control element, managing fluid pressure and flow within the valve body assembly to ensure precise gear engagement. As an integral part of the transmission’s shift logic, the 6073.015.071 works in concert with the 4657101082: TRANSMISSION HOUSING to maintain consistent hydraulic pressure across all operating conditions. The SKU 6073.015.071 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and reliable performance in heavy-duty industrial applications.
Symptoms of Failure
- Erratic shift timing and gear hunting: When the 6073.015.071 wears, hydraulic pressure fluctuates, causing the transmission to delay or rush shifts, particularly under load.
- Oil seepage around the valve body area: Degraded seals on this part lead to visible fluid leaks, often mistaken for housing cracks. This is a common long-tail search query for “ZF WG190 oil leak valve body.”
- Intermittent gear slipping during acceleration: Worn internal bores fail to hold pressure, resulting in momentary loss of drive in forward or reverse gears.
- Harsh or clunking engagements: A failing 6073.015.071 disrupts the modulation of clutch pack pressure, producing jarring shifts that worsen as the transmission warms up.

Compatibility
This OEM genuine part is primarily engineered for the ZF WG 190 series transmission. It is also compatible with the WG 180 and WG 200 series models that share the same valve body architecture. The 6073.015.071 interfaces directly with the 4657201166: HOUS.FRONT SECT and the 4657201170: HOUSING REAR PART to form a sealed hydraulic circuit. For applications requiring additional structural support, the 4657298102: HOUSING REAR SECTION is often replaced concurrently. Always verify your transmission’s serial number against ZF’s compatibility charts before installation.

Frequently Asked Questions
Q: Can the 6073.015.071 be replaced without removing the transmission?
A: Yes, in most WG190 installations, this part is accessible after draining the fluid and removing the valve body cover. However, access may be restricted on vehicles with tight chassis clearance. Always consult the ZF service manual for your specific model.
Q: How do I confirm this is the correct part for my WG190?
A: Verify the stamped part number on your existing component matches 6073.015.071. Additionally, check that your transmission serial number falls within the WG190 range (typically beginning with “WG190” or “WG19”).
Q: What torque specification should I use for the mounting bolts?
A: ZF recommends 25 Nm (18.4 ft-lbs) for the M6 bolts securing this component. Always use new sealing washers and apply thread locker to prevent loosening from vibration.
