Overview
The ZF 4644.199.482 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 200 Series transmission. This OEM genuine part contains the essential fasteners, seals, and small components required to secure and seal the transmission housing during rebuilds or major repairs. The SKU 4644.199.482 is typically installed in conjunction with the 4644101275: TRANSMISSION HOUSING and the 4644301406: TRANSMISSION HOUSING to ensure a leak-free, vibration-resistant assembly. Without this loose parts set, the internal hydraulic circuits and gear train cannot maintain proper pressure, leading to performance degradation.
Symptoms of Failure
- External oil seepage at housing joints: When the fasteners and seals in this kit degrade, transmission fluid may weep from the mating surfaces between the housing and cover plates, leaving visible drips under the vehicle.
- Intermittent gear slippage under load: Loose or missing hardware from the 4644.199.482 set can cause the valve body or shift system to shift out of alignment, resulting in delayed engagement or slipping during acceleration.
- Abnormal transmission noise or vibration: Worn-out retaining components allow the 0730301612: TYPE PLATE and 4644301298: COVER PLATE to rattle, producing a distinct metallic chatter during gear changes.
- Contaminated fluid from debris ingress: A compromised seal in this loose parts kit permits dirt and moisture to enter the transmission, accelerating internal wear and reducing fluid life.

Compatibility
This loose parts kit is engineered primarily for the ZF WG 200 Series transmissions, including the WG200, WG210, and WG180 variants. It also applies to certain WG 180 Series units that share the same housing bolt pattern and seal geometry. The kit is not interchangeable with older WG 150 or WG 120 models due to different fastener thread pitches. Always verify your transmission model against the 0730301612: TYPE PLATE to confirm fitment before ordering.
