Overview
This complete ZF 4657.054.061 4 WG 210 Powershift Transmission Assembly is a fully integrated unit designed for heavy-duty industrial applications. As the core power transfer module in the WG 210 series, this assembly manages torque distribution across four forward speeds and multiple reverse ranges, ensuring smooth clutch engagement under load. The SKU 4657.054.061 replaces the entire gear train and hydraulic control system, making it a direct drop-in solution for machinery requiring a complete overhaul. It interfaces directly with the TRANSMISSION HOUSING to form the main structural envelope, while the HOUS.FRONT SECT and HOUSING REAR PART secure the internal planetary sets.
Symptoms of Failure
- Delayed or harsh shifting under load: Worn clutch packs or valve body degradation cause hesitation when engaging forward or reverse gears, often accompanied by a loud clunk.
- Internal oil leaks and low pressure: Cracks in the main casing or failed seals lead to visible fluid drips and a drop in hydraulic pressure, triggering warning lights on the dash.
- Gear slipping during acceleration: The transmission loses torque transfer in higher ranges, causing the engine to rev without proportional vehicle movement, especially on inclines.
- Unusual whining or grinding noises: Bearing wear or damaged planetary gears produce metallic sounds that intensify with speed, indicating imminent internal failure.

Compatibility
This complete unit is engineered for the ZF WG 210 series, but it also fits select WG 180 and WG 200 variants when used with the correct adapter kit. It is a direct replacement for models: WG 210-4, WG 210-6, and WG 210-8. For older WG 180 units, verify the bellhousing pattern matches the TRANSMISSION HOUSING flange. The assembly is not compatible with WG 120 or WG 150 series without significant modification. Always cross-reference the CYLINDRICAL PIN alignment before installation.

Frequently Asked Questions
Q: Is the 4657.054.061 a remanufactured or new unit?
A: This is a brand-new complete assembly, not a remanufactured unit. It includes all internal clutches, seals, and bearings pre-installed.
Q: Can I install this unit without removing the HOUS.FRONT SECT?
A: No. The front section must be separated to align the input shaft splines. We recommend replacing the CYLINDRICAL PIN during reassembly to ensure proper alignment.
Q: What is the typical lead time for this complete unit?
A: Most orders ship within 5-7 business days. Expedited shipping is available upon request.
