Overview
The ZF 4642.199.297 LOOSE PARTS kit is a critical service component designed specifically for the WG 200 Series transmission. This OEM genuine assembly contains the essential fasteners, seals, and small hardware required to secure internal sub-assemblies during a rebuild or major repair. Positioned within the main valve body and clutch housing interface, this kit ensures that all loose components remain properly torqued and aligned under high hydraulic pressure. The SKU 4642.199.297 is the direct replacement for the original factory loose parts set, eliminating guesswork during transmission overhaul.
Symptoms of Failure
When the 4642.199.297 LOOSE PARTS begin to degrade or are missing, operators often notice intermittent gear slippage under load, particularly during upshifts between second and third gear. A second common symptom is low hydraulic pressure accompanied by erratic shift timing, which can trigger fault codes in the TCU. You may also experience metallic rattling noises from the bell housing area as loose hardware contacts the rotating clutch pack. Finally, chronic oil seepage around the valve body cover indicates that the included seals in this kit have hardened or cracked.

Compatibility
This LOOSE PARTS kit is engineered primarily for the ZF WG200 transmission series, including the WG210 and WG220 variants. It also fits select WG180 models where the valve body and clutch housing share the same bolt pattern and seal dimensions. For confirmation, always cross-reference your transmission serial number with the OEM parts catalog. The kit integrates directly with the 4644101180: TRANSMISSION HOUSING and the 4644301225: TRANSMISSION HOUSING to ensure proper alignment of the shift mechanism.
During installation, the 0730365067: TYPE PLATE must be affixed to the housing after the loose parts are torqued, and the 0631311009: GROOVED STUD is used to anchor the valve body cover. These components work in concert to prevent hardware migration and maintain oil circuit integrity.
