ZF 4661.042.011 2 WG 94 Powershift Transmission Assembly | Complete Unit

Overview

The ZF 4661.042.011 2 WG 94 Powershift Transmission Assembly | Complete Unit is a fully assembled, drop-in replacement designed for heavy-duty powershift applications. This complete unit integrates the main gear cluster, clutch packs, and hydraulic control elements into a single, pre-tested assembly. As the core rotating and shifting component within the WG 94 Series, it directly governs torque delivery and gear selection. The SKU 4661.042.011 is precision-machined to OEM tolerances, ensuring seamless integration with the TRANSMISSION HOUSING and the HOUSING II to form a leak-free, high-torque driveline.

Symptoms of Failure

• Erratic gear engagement or slipping under load: Worn clutch discs or piston seals within the assembly cause delayed or incomplete shifting, especially during high-torque maneuvers.
• Internal hydraulic pressure loss: Degraded O-rings or valve body wear lead to low line pressure, resulting in soft shifts and eventual transmission overheating.
• Metallic debris in the oil pan: Bearing or gear tooth spalling generates fine metal particles, which can clog the filter and damage the CYLINDRICAL PIN guides.
• Audible whining or grinding from the bell housing: Worn input shaft bearings or misaligned planetary gears produce distinct noise that worsens with RPM changes.

Technical Specifications

Compatibility

This complete unit is engineered for the WG 94 Series of ZF powershift transmissions. It is directly compatible with the following models and their derivatives:

• ZF WG180 – 6-speed powershift for wheel loaders and graders
