ZF 4657.056.183 6 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

The ZF 4657.056.183 6 WG 210 Powershift Transmission Assembly | Complete Unit is a fully assembled, direct replacement gearbox designed for heavy-duty off-highway applications. This complete unit integrates the main housing, clutch packs, and hydraulic control system into a single, ready-to-install assembly. The SKU 4657.056.183 serves as the core power transfer component in the WG 210 series, sitting between the engine flywheel and the final drive. For a full rebuild, ensure the 4657101082: TRANSMISSION HOUSING is inspected for cracks, and verify the integrity of the 4657201166: HOUS.FRONT SECT which seals the front clutch assembly.

Symptoms of Failure

• Delayed engagement or gear slipping under load: When the internal clutches or valve body wear, the transmission hesitates before engaging forward or reverse, or slips during heavy pulling.
• External oil leaks at the housing seams: Worn gaskets or cracked castings on the 4657201170: HOUSING REAR PART cause hydraulic fluid to weep, leading to low pressure and overheating.
• Erratic shifting or harsh engagement: A failing torque converter or worn piston seals within the assembly produce jarring shifts or unintended neutral conditions.
• Overheating and burnt fluid smell: Internal wear generates excessive heat, oxidizing the transmission oil and producing a distinct burnt odor.

Technical Specifications

Compatibility

This complete assembly is engineered for the ZF WG 210 series. It is directly compatible with the WG 210, WG 200, and WG 180 transmission models used in telehandlers, wheel loaders, and dump trucks.
