Overview
The ZF 4616.006.007 6 WG 65 Powershift Transmission Assembly is a complete, factory-matched unit designed for heavy-duty off-highway machinery. 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 in the WG 65 series, it replaces the entire internal rotating assembly. The SKU 4616.006.007 is a direct OEM reference for this complete unit, ensuring precise fitment and original performance specifications. It sits directly within the TRANSMISSION HOUSING, which provides structural support and fluid containment for the assembly.
Symptoms of Failure
- Erratic gear engagement or slipping under load: When the internal clutch packs or hydraulic seals degrade, the transmission may hesitate, shudder, or fail to hold a gear during heavy operation.
- Internal hydraulic pressure loss: Worn sealing rings or damaged valve bodies within the assembly can cause low line pressure, leading to delayed shifts or complete loss of drive.
- Contaminated transmission fluid with metallic debris: Bearing or gear wear inside the 4616.006.007 unit produces fine metal particles in the oil, often visible during routine filter changes.
- Audible whining or grinding from the bell housing: Damaged planetary gears or thrust washers generate distinct noise that increases with engine RPM, indicating imminent internal failure.

Compatibility
This complete assembly is engineered for the ZF WG 65 series of powershift transmissions. It is directly compatible with models including the WG180, WG200, and WG250, which share the same 6-speed planetary architecture and mounting interface. The unit also fits select variants of the WG120 and WG150 where the 4616.006.007 is specified as the replacement core. For proper installation, ensure the OUTPUT shaft and OUTPUT FLANGE are inspected for wear, and secure the assembly using the correct HEXAGON SCREW fasteners.
