ZF 6057.018.794 for WG160 | OEM Genuine Part

Overview

The ZF 6057.018.794 is a precision-engineered OEM genuine component specifically designed for the WG 160 Series transmission. This part serves as a critical sealing and alignment element within the hydraulic control circuit, ensuring proper fluid routing and pressure regulation during gear shifts. Positioned between the main valve body and the transmission housing, the 6057.018.794 prevents cross-contamination of oil passages and maintains the integrity of the lubrication system. As an OEM genuine part, it guarantees exact fitment and material compatibility with the original ZF design specifications, reducing the risk of premature wear in adjacent assemblies such as the TRANSMISSION HOUSING and the HOUS.FRONT SECT.

Symptoms of Failure

When the ZF 6057.018.794 begins to degrade, operators may notice several distinct performance issues. Oil seepage around the transmission bell housing is a common early indicator, often mistaken for a simple gasket failure. Delayed or harsh engagement between forward and reverse gears occurs as fluid pressure bleeds past the worn component. Another frequent complaint is intermittent gear slipping under load, particularly when towing or climbing grades, which can be traced back to insufficient hydraulic pressure. Finally, contaminated transmission fluid with metallic debris may appear if the part fractures, allowing wear particles from the HOUSING REAR PART to circulate through the system.

Technical Specifications

Compatibility

This OEM genuine part is engineered for the ZF WG 160 Series transmission family. It is directly compatible with the WG160, WG180, and WG200 models, as well as select variants of the WG150 and WG210 that share the same hydraulic control architecture. The 6057.018.794 interfaces seamlessly with the HOUSING REAR SECTION and the main valve body. For applications outside the WG series, always verify dimensional compatibility using the specifications above. This part is not recommended for use in ZF Ecomat or AS Tronic transmissions without adapter kits.

Frequently Asked Questions

Q: Can I install the 6057.018.794 without removing the transmission from the vehicle?
A: In most WG160 applications, this part is accessible after removing the transmission oil pan and valve body. However, for rear-mounted configurations, partial transmission removal may be required. Always consult the ZF service manual for your specific model.

Q: How does this part differ from aftermarket alternatives?
A: The OEM genuine 6057.018.794 uses ZF-specified steel hardness and surface finish tolerances that aftermarket parts often fail to replicate. Using non-OEM components can lead to accelerated wear of the HOUS.FRONT SECT and increased oil bypass.

Q: What is the typical service life of this component?
A: Under normal operating conditions with proper fluid maintenance, the 6057.018.794 lasts between 250,000 and 400,000 miles. Severe duty cycles or contaminated fluid can reduce this lifespan by up to 40%.
