Overview
The ZF 4657.183.216 LOOSE PARTS for WG210 is a critical internal component kit designed specifically for the WG 210 series transmission. This genuine OEM part serves as a collection of essential fasteners, seals, and positioning elements that secure the transmission’s main housing assembly. Located within the central casing structure, the SKU 4657.183.216 ensures that the TRANSMISSION HOUSING remains properly aligned with the HOUS.FRONT SECT and the HOUSING REAR PART. Without these loose parts, the transmission cannot maintain structural integrity under load.
Symptoms of Failure
- Transmission fluid seepage at casing joints: When the 4657.183.216 kit’s fasteners loosen or seals degrade, oil begins to weep from the seam between the front and rear housing sections.
- Intermittent gear engagement hesitation: Worn positioning pins within this loose parts set allow the HOUSING REAR PART to shift microscopically, causing delayed clutch pack engagement during upshifts.
- Abnormal vibration during torque converter lockup: Loose fixing elements from the kit create micro-movement between the housing sections, translating into driveline shudder at highway speeds.
- Difficulty maintaining hydraulic pressure: A compromised seal from degraded loose parts leads to internal pressure loss, often flagged by diagnostic trouble codes for low line pressure.

Compatibility
This genuine ZF 4657.183.216 loose parts kit is engineered for the WG 210 series transmission family. Based on its structural role, it is also compatible with the closely related WG180 and WG200 models that share the same housing architecture. The kit directly interfaces with the TRANSMISSION HOUSING and both the HOUS.FRONT SECT and HOUSING REAR PART assemblies. For applications using the HOUSING REAR PART variant, verify the specific bolt pattern before installation.

Frequently Asked Questions
Q: Can I reuse the existing bolts from my old loose parts kit?
A: No. The ZF 4657.183.216 kit includes new fasteners with pre-applied thread locker. Reusing old bolts risks improper torque retention and subsequent oil leaks.
Q: Does this kit include the gaskets for the housing joint?
A: Yes. The loose parts set contains all necessary O-rings and sealing washers for the interface between the TRANSMISSION HOUSING and the HOUS.FRONT SECT. Separate gaskets are not required.
Q: Is this part compatible with the WG180 transmission?
A: Yes. While primarily designed for the WG210, the 4657.183.216 kit shares identical bolt patterns and seal dimensions with the WG180 and WG200 series, making it a direct fit for those models as well.
