Overview
This complete ZF 4657.024.106 4 WG 190 Powershift Transmission Assembly is a fully integrated unit designed for heavy-duty industrial applications. As the core drivetrain component, it manages torque distribution and gear selection under high-stress conditions. The SKU 4657.024.106 replaces the entire transmission assembly, ensuring seamless power flow from the engine to the wheels. This unit sits at the center of the powertrain, directly connecting to the 4657101051: TRANSMISSION HOUSING and the 4657201151: HOUS.FRONT SECT, which together form the structural backbone of the gearbox.
Symptoms of Failure
- Delayed or harsh gear engagement – When the assembly wears, operators often report a noticeable lag or clunking sensation when shifting between forward and reverse, especially under load.
- Internal oil leaks – Worn seals within the unit can cause transmission fluid to pool around the bell housing or drip from the 4657201103: HOUSING REAR PART, leading to low fluid levels and overheating.
- Torque converter shudder – A vibrating or shuddering sensation during acceleration at low speeds indicates internal clutch pack wear or hydraulic pressure loss within the 4 WG 190 assembly.
- Complete loss of drive – In advanced failure stages, the transmission may fail to engage any gear, often traced to a cracked 4472239184: HOUSING REAR PART or damaged planetary gears.

Compatibility
This complete unit is engineered for the ZF WG 190 series, but it also fits select models in the WG 180 and WG 200 families due to shared housing bolt patterns. Specifically, it is compatible with ZF 4 WG 180, ZF 4 WG 190, and ZF 4 WG 200 transmissions used in construction loaders, forklifts, and agricultural tractors. Always verify the TRANSMISSION HOUSING part number before installation to ensure a proper fit with the HOUS.FRONT SECT and rear housing components.
