ZF 6057.018.114 for WG115 | OEM Genuine Part

Overview

This OEM genuine ZF 6057.018.114 component is a critical internal seal and guide element specifically engineered for the WG 115 Series transmission. Positioned within the valve body or hydraulic control unit, this part ensures precise oil flow regulation and pressure stability during gear shifts. The SKU 6057.018.114 is manufactured to original ZF tolerances, guaranteeing a direct fit and long service life. When installed alongside a properly sealed TRANSMISSION HOUSING, this part prevents cross-port leakage that can degrade shift quality.

Symptoms of Failure

• Erratic or delayed shifting – Worn 6057.018.114 components cause inconsistent hydraulic pressure, leading to hesitation when moving from neutral to drive or reverse.
• Internal transmission oil leaks – Degraded sealing surfaces allow ATF to bypass internal circuits, often visible as wet spots near the valve body area or a persistent low fluid level.
• Harsh engagement or gear slipping – As the part loses its dimensional integrity, clutch pack engagement becomes abrupt, or the transmission may momentarily lose power under load.
• Whining or buzzing noises from the transmission – Air entrainment caused by a failing seal element can produce high-pitched sounds, particularly during cold starts or low-speed operation.

Technical Specifications

Compatibility

This genuine ZF part is designed primarily for the WG 115 Series transmission family. It is also compatible with select models in the WG180 and WG200 series that share the same valve body architecture. Always verify your transmission model number before ordering. For complete assembly integrity, this component works in conjunction with the HOUS.FRONT SECT and the HOUSING REAR PART to maintain structural alignment. In certain WG115 configurations, it also interfaces with the HOUSING REAR PART (variant 4472239178) for additional sealing support.

Frequently Asked Questions

Q: Can the 6057.018.114 be replaced without removing the entire transmission?
A: In most WG115 applications, this component is accessible after removing the transmission oil pan and valve body. However, due to its position within the hydraulic circuit, we recommend consulting the ZF service manual for your specific model to confirm access requirements.

Q: How do I know if my transmission uses the 6057.018.114 or a different seal variant?
A: Check the part number stamped on the valve body or refer to your transmission’s parts catalog. The 6057.018.114 is specific to WG115 series units built after 2012. Earlier models may use a different diameter seal.

Q: Is this part interchangeable with aftermarket alternatives?
A: While aftermarket seals may fit dimensionally, only the OEM genuine ZF 6057.018.114 is manufactured to the exact material hardness and surface finish required for long-term reliability in high-pressure hydraulic circuits. We strongly recommend using genuine parts to avoid premature failure.
