Overview
The ZF 4661.043.014 3 WG 94 Powershift Transmission Assembly is a complete, factory-matched unit designed for heavy-duty off-highway machinery. This assembly integrates the core hydraulic and mechanical components of the WG 94 series, providing seamless gear engagement under load. As a complete unit, the SKU 4661.043.014 replaces the need for individual sub-assembly procurement, ensuring precise alignment of clutches, shafts, and valve bodies. It sits centrally within the driveline, converting engine torque into controlled power output for construction and agricultural equipment. For optimal sealing and structural integrity, this assembly is paired with the 4661101033: HOUSING and the 4661301096: HOUSING, which enclose the rotating components.
Symptoms of Failure
- Erratic gear engagement or slipping under load: When the complete unit wears, internal clutch pack clearances increase, causing delayed or harsh shifts during operation.
- External oil leaks at housing seams: Degraded seals within the assembly allow hydraulic fluid to escape, often visible around the mating surfaces of the 0631306174: CYLINDRICAL PIN alignment points.
- Loss of power to the wheels or PTO: Internal pressure loss from worn valve bodies or piston rings results in insufficient torque transfer, particularly in reverse or low-range gears.
- Unusual whining or grinding noises: Bearing wear or debris contamination within the assembly creates audible distress, often accompanied by metallic particles in the oil filter.

Compatibility
This complete unit is engineered for the ZF WG 94 series, which includes the WG180, WG200, and WG211 transmission models commonly found in telehandlers, wheel loaders, and industrial tractors. It directly replaces the 3-speed powershift variant used in applications requiring a compact, high-torque drivetrain. The assembly is also compatible with earlier WG 92 series housings when used with the correct 0769123894: TYPE PLATE for identification. Always verify the bellhousing pattern and input shaft spline count before installation.
