Overview
This complete ZF 4657.024.041 4 WG 190 Powershift Transmission Assembly is a fully assembled drop-in unit designed for heavy-duty off-highway applications. As the core power transfer module in the WG 190 series, this assembly integrates the torque converter, planetary gear sets, and hydraulic control system into a single, ready-to-install package. The SKU 4657.024.041 replaces worn or failed transmissions in wheel loaders, dozers, and material handlers, restoring full forward/reverse shuttle capability and load-sensing performance. This unit is precision-balanced and pressure-tested to OEM specifications, ensuring reliable operation under extreme loads.
Symptoms of Failure
- Delayed or harsh engagement: When the transmission hesitates before engaging forward or reverse, or slams into gear, the internal clutch packs and seals within the 4657.024.041 assembly are likely worn.
- Loss of power under load: If the machine struggles to climb grades or move heavy material, the torque converter or planetary gear set inside this WG 190 unit may be slipping due to internal leakage or worn friction discs.
- External oil leaks at the bell housing or rear seal: Visible drips or puddles of transmission fluid near the engine-transmission interface indicate a failed input seal or housing crack, requiring replacement of the complete assembly.
- Erratic shifting or neutral creep: Unintended movement when the transmission is in neutral, or inconsistent shift points, point to valve body wear or hydraulic circuit failure within the 4657.024.041.

Always verify the transmission serial number against the original equipment manufacturer’s parts list before installation.
Related Components
When installing the 4657.024.041 complete unit, several surrounding components should be inspected and replaced to ensure a leak-free, durable rebuild. The TRANSMISSION HOUSING (4657101033) provides the structural backbone and must be free of cracks. The HOUS.FRONT SECT (4657201027) and HOUSING REAR PART (4657201012) seal the clutch packs and planetary sets. A CYLINDRICAL PIN (0631306792) aligns the housing sections during assembly.
