Overview
The ZF 4657.056.082 6 WG 210 Powershift Transmission Assembly is a complete, factory-matched unit designed for heavy-duty off-highway applications. This assembly integrates the main gear cluster, clutch packs, and hydraulic control components into a single ready-to-install package. As the core power transfer module for the WG 210 series, it replaces the entire rotating assembly inside the main case. The SKU 4657.056.082 is a direct OEM-specification unit, ensuring precise fitment with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain correct gear alignment and oil flow.
Symptoms of Failure
- Delayed or harsh shifting under load: Worn clutch packs inside the assembly cause hesitation or jarring engagement, especially when moving from forward to reverse.
- Internal oil leaks and low pressure: Degraded seals between the assembly and the HOUSING REAR PART lead to visible drips from the bell housing and a drop in hydraulic pressure.
- Metallic grinding or whining noise: Failed bearings or gear tooth damage produce a constant high-pitched sound that worsens with speed, indicating imminent internal seizure.
- Transmission overheating: Slipping clutches generate excess heat, causing the oil to darken and the unit to enter thermal protection mode.

Compatibility
This complete assembly is engineered for the ZF WG 210 series, specifically the 6-speed powershift variant. It is directly compatible with the following transmission models: WG 180 (late production with 6-speed upgrade), WG 200, and WG 210 (all sub-variants).
