Overview
The ZF 4616.000.217 4 WG 65 Powershift Transmission Assembly is a complete, remanufactured unit designed for heavy-duty off-highway applications. This assembly integrates the full gear train, clutch packs, and hydraulic control system within a robust housing. As a core component of the WG 65 series, it manages torque distribution across four forward and reverse speeds. The SKU 4616.000.217 is a direct replacement for OEM assemblies, ensuring seamless integration with existing drivelines. This complete unit eliminates the need for piecemeal repairs, providing a drop-in solution for construction, mining, and agricultural machinery.
Symptoms of Failure
- Delayed or harsh engagement: When the assembly wears, you may experience a noticeable lag or a jarring shift when moving from neutral to drive or reverse, often accompanied by a loud clunk.
- Internal oil leaks and low pressure: Worn seals or a cracked TRANSMISSION HOUSING can cause fluid to pool externally or bypass internally, leading to slipping under load and erratic shift patterns.
- Loss of power in specific gears: A failing clutch pack or damaged planetary set within the assembly will cause the machine to lose pulling power or fail to move in one or more gear ranges.
- Unusual whining or grinding noises: Bearing wear or gear tooth damage inside the unit produces a high-pitched whine or a low grinding sound, particularly during acceleration or deceleration.

Compatibility
This complete unit is engineered for the ZF WG 65 series of powershift transmissions. It is a direct fit for models including the WG65, WG80, WG100, and WG120. While primarily designed for the WG 65 platform, the assembly shares mounting patterns and hydraulic interfaces with the WG180 and WG200 series when used with the correct adapter HOUSING (part 4616301304) or the alternative HOUSING (part 4616301309). Always verify your transmission model and serial number before installation.
