Overview
This OEM genuine ZF 6057.014.076 component is a precision-engineered part designed for the WG 158 series transmission. It functions as a critical interface within the clutch pack assembly, ensuring proper hydraulic pressure distribution and mechanical alignment during gear engagement. The SKU 6057.014.076 is manufactured to ZF’s exacting tolerances, providing reliable performance in heavy-duty commercial vehicle applications. When installed alongside the TRANSMISSION HOUSING, it maintains the structural integrity required for sustained torque transfer under load.
Symptoms of Failure
- Delayed or harsh shifting – Worn 6057.014.076 components can cause hesitation between gear changes, often accompanied by a noticeable jolt when engaging forward or reverse.
- Low transmission fluid pressure – Internal wear may lead to hydraulic leaks, resulting in a drop in line pressure that triggers warning lights on the dashboard.
- Unusual whining or grinding noises – As the part degrades, metal-on-metal contact produces audible sounds during acceleration or deceleration, particularly in lower gears.
- Intermittent gear slippage – A failing unit can cause the transmission to momentarily lose power delivery, especially when climbing grades or carrying heavy loads.

Compatibility
This genuine ZF 6057.014.076 part is specifically engineered for the WG 158 transmission series. It is also compatible with select variants in the WG180 and WG200 families, provided the transmission uses the same clutch pack architecture. For proper fitment, always verify the part number against your transmission’s serial plate. The SHIFT SYSTEM and SCREW-IN SLEEVE must be inspected concurrently, as wear in these adjacent assemblies can accelerate degradation of the 6057.014.076.

Frequently Asked Questions
Q: How do I know if the 6057.014.076 needs replacement?
A: Monitor for fluid leaks near the clutch housing or erratic shift patterns. A visual inspection often reveals scoring or pitting on the part’s mating surface.
Q: Can I install this part without replacing the GEAR SHIFT HOUSING?
A: Yes, but we recommend inspecting the shift housing for wear simultaneously, as misalignment can reduce the lifespan of the new 6057.014.076.
Q: Is this part interchangeable with WG180 transmissions?
A: It fits WG180 models that share the same clutch pack design. Always cross-reference your transmission’s serial number with ZF’s compatibility chart before ordering.
