Overview
The ZF 4657.056.113 6 WG 210 Powershift Transmission Assembly represents a complete, factory-grade replacement unit designed for heavy-duty off-highway applications. This fully assembled transmission integrates the planetary gear sets, clutch packs, and hydraulic control system into a single ready-to-install package. As a core component of the WG 210 series, this assembly governs torque distribution across six forward speeds and one reverse speed. The SKU 4657.056.113 is precision-matched to OEM specifications, ensuring seamless integration with existing driveline components. The unit sits between the engine flywheel housing and the final drive, with the TRANSMISSION HOUSING forming the structural backbone that encloses all rotating elements.
Symptoms of Failure
- Erratic gear engagement under load: When the assembly wears, operators experience delayed or harsh shifting during uphill climbs or heavy pulling, often accompanied by a grinding noise from the clutch packs.
- Hydraulic fluid contamination: Internal seal degradation allows metal particles to circulate, causing the transmission to slip intermittently and triggering low-pressure warnings on the dash display.
- Oil leaks at housing joints: Cracks or warpage in the HOUS.FRONT SECT or HOUSING REAR PART lead to visible drips near the bell housing, reducing fluid levels and accelerating component wear.
- Complete loss of reverse gear: A failing torque converter or damaged planetary carrier within the assembly prevents reverse engagement, requiring immediate unit replacement to avoid secondary damage.

Compatibility
This complete unit is engineered for the ZF WG 210 series, but its mounting pattern and hydraulic interface also suit the WG 180 and WG 200 families when paired with the correct HOUSING REAR SECTION. Specifically, the 4657.056.113 fits the 6 WG 210, 6 WG 200, and 6 WG 180 transmissions used in wheel loaders, telehandlers, and dump trucks from manufacturers such as Liebherr, JCB, and Caterpillar (models with ZF drivelines). Always verify the bell housing pattern—the HOUS.FRONT SECT must match your engine flywheel housing SAE 3 or SAE 4 standard.
