Overview
The ZF 4642.199.495 LOOSE PARTS is a critical OEM genuine service kit designed specifically for the WG 200 series transmission. This assembly group contains the necessary loose components—including seals, retainers, and small hardware—that secure and stabilize internal shift mechanisms within the transmission housing. As a precision-engineered set, the 4642.199.495 ensures that the shift system and valve block maintain correct alignment under high torque loads. Without these loose parts, the transmission housing cannot properly contain hydraulic pressure, leading to operational inefficiency. This SKU is frequently ordered alongside the 4644101235: TRANSMISSION HOUSING and the 4644301310: TRANSMISSION HOUSING to complete a full rebuild of the WG200 assembly.
Symptoms of Failure
- Intermittent gear slipping under load – When the loose parts wear, the shift system loses its positional tolerance, causing the transmission to slip out of gear during heavy acceleration or climbing.
- Hydraulic fluid seepage around the housing joint – Degraded seals within the 4642.199.495 kit allow ATF to escape, leaving visible drips on the bell housing and undercarriage.
- Delayed or harsh engagement – Worn retainers prevent the valve block from seating correctly, resulting in a noticeable lag when shifting from neutral to drive or reverse.
- Unusual metallic rattling from the transmission pan – Loose hardware inside the assembly can vibrate against the 0730365067: TYPE PLATE, creating a distinct noise that worsens with RPM.

Compatibility
This genuine ZF loose parts kit is primarily engineered for the WG 200 series transmissions, including the WG200, WG210, and WG220 variants. It is also backward-compatible with select WG180 models that share the same shift system interface. The 4642.199.495 directly interfaces with the 4644106301: SHIFT SYSTEM and the valve block assembly. For complete transmission overhaul, always verify that your housing casting matches the WG200 footprint, as earlier WG160 units require a different retainer set.
