Overview
The ZF 6073.017.239 is a critical OEM genuine component engineered specifically for the WG 160 series transmission. This part functions as a precision-machined internal guide or actuator element within the valve body assembly, regulating hydraulic fluid flow to ensure smooth clutch engagement and gear shifts. The SKU 6073.017.239 is manufactured to ZF’s exacting tolerances, guaranteeing direct fitment and long service life. When installed alongside the 4656201085: HOUS.FRONT SECT, it forms a sealed hydraulic circuit that prevents cross-leakage between pressure channels.
Symptoms of Failure
- Delayed or harsh shifting: A worn 6073.017.239 causes erratic hydraulic pressure, leading to hesitation when shifting from neutral to drive or reverse.
- Internal transmission oil leaks: Degraded sealing surfaces allow ATF to bypass the valve body, resulting in low fluid levels and puddles under the bell housing.
- Gear slipping under load: When the part loses its dimensional integrity, clutches fail to hold torque, causing RPM flare during acceleration.
- Erratic shift patterns: The transmission may skip gears or hunt between ratios due to inconsistent pilot pressure from a failing 6073.017.239.

Compatibility
This genuine ZF part is designed for the WG 160 series transmission family. It is also compatible with the WG 180 and WG 200 models when used in conjunction with the correct 0631306816: CYLINDRICAL PIN and 4656301148: FIXING PLATE. For secure mounting, always pair with the 0636100817: CAP SCREW to achieve proper torque specifications. The 6073.017.239 is not interchangeable with earlier WG 120 series parts due to different bore diameters.

Frequently Asked Questions
Q: How do I know if the 6073.017.239 is the correct part for my WG 160 transmission?
A: Verify the stamped part number on the original component. This part is exclusive to WG 160 series units built after 2012. Cross-reference with your transmission serial number to confirm compatibility.
Q: Can I install this part without replacing the fixing plate and cap screws?
A: ZF recommends replacing the 4656301148: FIXING PLATE and 0636100817: CAP SCREW simultaneously to maintain clamping force and prevent future loosening due to thermal cycling.
Q: What is the typical lifespan of the 6073.017.239 under normal operating conditions?
A: With proper maintenance and clean ATF, this OEM part typically lasts 200,000 to 300,000 miles. Early replacement is advised if any shift quality issues arise.
