Overview
The ZF 4657.056.013 6 WG 210 Powershift Transmission Assembly represents a complete, drop-in replacement unit engineered for heavy-duty off-highway applications. This fully assembled gearbox integrates the torque converter, clutch packs, and hydraulic control system into a single ready-to-install package. As a core component of the WG 210 Series, this assembly manages power distribution from the engine to the driveline, enabling smooth directional shifts and precise speed control under extreme load conditions. The SKU 4657.056.013 is specifically designed to restore original ZF performance in wheel loaders, telehandlers, and industrial tractors where downtime is critical.
Symptoms of Failure
When the ZF 4657.056.013 assembly begins to degrade, operators will notice distinct operational issues. Recognizing these signs early can prevent catastrophic driveline damage.
- Delayed or harsh engagement: A noticeable lag when shifting from forward to reverse, or a jarring clunk upon gear engagement, indicates worn clutch discs or degraded hydraulic pressure within the unit.
- Transmission overheating under light load: If the gearbox temperature spikes during normal operation, it often points to internal seal failure or a failing torque converter stator, causing excessive fluid shear.
- Oil leaks from the bell housing or output flange: Visible drips of ATF or hydraulic oil around the transmission case, particularly near the pump drive or PTO cover, signal worn shaft seals or housing cracks in the assembly.
- Loss of power or gear slipping: The engine revs freely but the machine fails to move, or it slips out of gear under load. This is a classic symptom of worn clutch packs or a failing hydraulic modulator valve inside the 4657.056.013.

Compatibility
This complete unit is engineered for the ZF WG 210 Series, but its mounting pattern and hydraulic interface allow it to serve as a direct replacement in several related ZF models. Verify your existing transmission tag before ordering.
- ZF WG 210 (primary application for SKU 4657.056.013)
- ZF WG 180 (with adapter plate modification for certain loader models)
- ZF WG 200 (common in older telehandlers; check bell housing bolt pattern)
- ZF 6 WG 200 (electro-hydraulic variants may require harness re-pinning)
- ZF WG 211 (limited compatibility; confirm output flange spline count)
Note: This assembly is not compatible with WG 120 or WG 150 series units. Always cross-reference your machine’s serial number with the ZF parts catalog to ensure proper fitment.
