Overview
The ZF 4657.056.214 6 WG 210 Powershift Transmission Assembly is a complete, factory-matched unit engineered for heavy-duty off-highway applications. This fully assembled gearbox integrates the main drive housing, clutch packs, and hydraulic control system into a single drop-in solution. As a core component of the WG 210 Series, it replaces worn or failed assemblies in wheel loaders, dump trucks, and industrial tractors. The SKU 4657.056.214 is a direct OEM-specification unit, ensuring precise alignment with the original drivetrain geometry. It sits as the central power transfer module between the engine and the final drive, managing torque distribution across six forward and three reverse gears.
Symptoms of Failure
- Delayed or harsh gear engagement: When the internal clutch packs or hydraulic seals degrade, operators experience a noticeable lag or jarring shift when moving from neutral to drive or reverse.
- Persistent transmission fluid leaks: Cracks in the main casing or worn gaskets around the TRANSMISSION HOUSING (4657101082) lead to visible oil seepage, especially near the bell housing or output shaft seal area.
- Torque converter shudder under load: A vibration or slipping sensation during acceleration indicates internal wear in the coupling assembly or damaged stator bearings.
- Loss of power in higher gears: Worn planetary gear sets or failing COUPLING (4657171030) components cause the transmission to struggle maintaining speed on inclines or under heavy payloads.

Compatibility
This complete assembly is specifically designed for the ZF WG 210 transmission series. It is directly compatible with models including WG180, WG200, and WG210. The unit also integrates with earlier WG160 variants when used with the correct TRANSMISSION HOUSING (4657101408) adapter. For applications requiring a different output configuration, the assembly accepts the COUPLING (4657172027) to match various driveline flanges. Always verify your existing transmission tag number before ordering.
