ZF 4657.055.115 5 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

The ZF 4657.055.115 5 WG 210 Powershift Transmission Assembly | Complete Unit is a fully integrated drop-in replacement for heavy-duty powershift applications. This complete assembly serves as the central power transfer hub, managing torque distribution across five forward gears in ZF’s WG 210 series. The SKU 4657.055.115 denotes a factory-matched unit that includes the main gear cluster, clutch packs, and hydraulic valve body. When installing this assembly, ensure the 4657101082: TRANSMISSION HOUSING is inspected for cracks, as the housing provides the structural foundation for the entire unit.

Symptoms of Failure

• Erratic gear engagement or slipping under load – Worn clutch packs inside the assembly cause delayed shifts or complete loss of drive in specific gears.
• Hydraulic oil leaks at the bell housing seam – Degraded seals between the transmission housing and front section allow pressurized ATF to escape, leaving puddles under the vehicle.
• Metallic grinding noise during gear changes – Damaged planetary gears or bearing races produce a distinct whine that worsens with RPM.
• Intermittent neutral condition – The transmission randomly drops into neutral due to internal valve body wear or a cracked 4657201166: HOUS.FRONT SECT.

Technical Specifications

Compatibility

This complete unit is engineered for the WG 210 series but shares mounting patterns with the WG180 and WG200 families. It directly replaces units in ZF 5WG-210, 5WG-200, and 5WG-180 transmissions used in loaders, graders, and industrial tractors. The assembly mates with the 4657201170: HOUSING REAR PART and the 4657298102: HOUSING REAR SECTION to complete the driveline enclosure. Always verify bell housing bolt patterns before installation.
