Overview
The ZF 4657.056.153 6 WG 210 Powershift Transmission Assembly | Complete Unit is a fully integrated, factory-built drop-in solution for heavy-duty off-highway machinery. This complete assembly serves as the core power transfer module in the WG 210 series, managing torque distribution across six forward speeds. The SKU 4657.056.153 identifies a remanufactured or new complete unit that includes the main housing, clutch packs, planetary gear sets, and hydraulic control valve body. It sits directly between the engine flywheel housing and the final drive, replacing the entire transmission assembly when catastrophic internal failure occurs. For proper installation, ensure the 4657101082: TRANSMISSION HOUSING is correctly aligned, as this unit bolts directly into that structural shell.
Symptoms of Failure
- Complete loss of forward or reverse drive: When the internal clutch packs or planetary gears fail, the transmission may refuse to engage any gear, leaving the machine immobile.
- Severe hydraulic fluid contamination: Worn friction material or broken metal fragments from the gear train will turn the transmission oil into a metallic sludge, visible during drain intervals.
- Erratic shifting or gear slippage under load: A failing complete unit often exhibits delayed engagement or sudden neutral drops when the machine is under heavy load, such as during grading or loading.
- External oil leaks from multiple seal points: Cracks in the 4657201166: HOUS.FRONT SECT or 4657201170: HOUSING REAR PART can cause pressurized oil to weep from the bell housing or rear output flange.

Compatibility
This complete unit is specifically engineered for the ZF WG 210 transmission family. It is directly compatible with the following ZF models: WG180, WG200, WG210, and WG250 series, provided the correct bell housing and output flange are used. The 4657.056.153 assembly is often specified for Case IH, New Holland, JCB, and Volvo CE loaders and graders that originally used the WG 210 platform. Always verify the housing sections—such as the 4657201166: HOUS.FRONT SECT and 4657201170: HOUSING REAR PART—match your machine’s chassis mounting points before installation.
