Overview
The ZF 4642.199.499 LOOSE PARTS kit is a critical service component engineered specifically for the WG 200 series transmission. This genuine OEM assembly includes all necessary fasteners, seals, and positioning elements required to secure internal sub-assemblies within the transmission housing. As a designated “loose parts” set, it ensures that the TRANSMISSION HOUSING (4644101232) and the TRANSMISSION HOUSING (4644301282) maintain proper alignment and clamping force during high-torque operations. The SKU 4642.199.499 is the definitive replacement for any missing or damaged hardware in the WG200 valve body and clutch pack retention area.
Symptoms of Failure
- Transmission oil seepage at housing joints: When the loose parts kit components fatigue, the seal between the main housing and cover plates degrades, leading to visible oil leaks around the bell housing.
- Intermittent gear slippage under load: Worn fasteners from this kit can cause the valve block to shift slightly, resulting in delayed engagement or slipping during acceleration.
- Abnormal rattling or vibration from the transmission casing: Loose retaining hardware allows internal components to vibrate against the housing, producing a distinct metallic noise at low RPM.
- Erratic shift timing: A compromised loose parts set can alter the hydraulic pressure distribution, causing harsh or delayed shifts between forward gears.

Compatibility
This genuine ZF 4642.199.499 loose parts kit is designed primarily for the WG 200 Series transmissions, including the WG200, WG210, and WG220 variants. It is also backward-compatible with the WG180 series when used in conjunction with the correct O-RING (0634306198) for sealing. For installations requiring a pressure-tight seal, always pair this kit with a new SCREW PLUG (4475280043) to prevent fluid bypass. The kit directly interfaces with the valve block and shift system assemblies found in these models.
