Overview
This ZF 4657.054.303 4 WG 210 Powershift Transmission Assembly is a complete, fully assembled unit designed for heavy-duty off-highway machinery. As the core hydraulic-mechanical power train component, it integrates the torque converter, planetary gear sets, and clutch packs into a single ready-to-install module. The SKU 4657.054.303 sits at the center of the driveline, directly coupling to the engine flywheel and transferring torque through the output shaft to the axle or transfer case. This assembly replaces the need for individual sub-component rebuilding, offering a drop-in solution for WG 210 series transmissions where the main casing or internal gear train has suffered catastrophic failure.
Symptoms of Failure
- Complete loss of forward or reverse drive: When the internal clutch drum or planetary carrier fractures, the transmission will fail to engage any gear, leaving the machine immobile despite engine RPM.
- Severe hydraulic oil contamination with metallic debris: Worn bearings or broken gear teeth generate large steel particles in the oil, visible on the dipstick or in the filter, indicating internal mechanical disintegration.
- Erratic shifting or gear slipping under load: A failing main shaft or worn splines cause intermittent power delivery, especially when the machine is under heavy load, leading to sudden lurching or RPM flare.
- External oil leaks from the main housing joint: Cracks in the TRANSMISSION HOUSING or warped mating surfaces allow pressurized ATF to escape, resulting in low fluid levels and eventual overheating.

Compatibility
This complete assembly is engineered for the ZF WG 210 series, but its internal architecture is shared across several ZF powershift models. It is a direct fit for the WG 180, WG 200, and WG 210 transmissions found in agricultural tractors, wheel loaders, and telehandlers. The unit also cross-references with the WG 160 series when used with the appropriate adapter plate. For proper installation, ensure the HOUS.FRONT SECT and HOUSING REAR PART align correctly with your machine’s bellhousing. If your application uses a split-case design, the HOUSING REAR SECTION must be ordered separately for multi-piece configurations.
