Overview
The ZF 2094.306.004 GEAR SHIFT FORK is a precision-engineered component designed for the WG100, WG130, and WG131 transmission series. This OEM genuine part acts as the mechanical interface between the shift system and the sliding gear, directing axial movement to engage specific gear ratios. Located within the transmission housing, the fork slides along a 2094104412: MAIN SHAFT to ensure precise gear selection. The SKU 2094.306.004 is manufactured to ZF’s exacting tolerances, guaranteeing a snug fit and reliable operation under heavy load conditions.
Symptoms of Failure
- Hard shifting or gear grinding: A worn shift fork fails to fully engage the synchronizer, causing audible grinding when moving between gears. This is a common long-tail search query for “ZF transmission hard shifting WG100.”
- Gear slipping under load: If the fork tines are bent or worn, the gear may pop out of engagement during acceleration, leading to sudden power loss.
- Oil contamination from metal debris: Excessive wear on the fork’s contact surfaces generates fine metallic particles in the transmission fluid, visible during routine oil changes.
- Erratic shift feel: A damaged fork can cause the shift lever to feel loose or imprecise, often accompanied by a “notchiness” when moving through the gate.

Compatibility
This shift fork is specifically engineered for ZF’s WG-series mechanical transmissions. It is a direct fit for the WG100, WG130, and WG131 models. While primarily designed for these three variants, it may also be compatible with certain WG180 and WG200 configurations that share the same shift rail spacing. Always verify by cross-referencing your existing part number. The fork interacts directly with the 2094206001: GEARSHIFT SHAFT and the 2094106010: SHIFT SYSTEM assembly to deliver smooth gear changes.

Frequently Asked Questions
Q: How do I know if my ZF 2094.306.004 shift fork is worn?
A: Inspect the fork tines for visible wear or a “shiny” polished area. If the fork has more than 0.5 mm of play on the shift rail, or if you experience gear grinding in only one direction (e.g., 3rd to 4th gear), replacement is recommended.
Q: Can I install this fork without removing the transmission?
A: No. The shift fork is an internal component. You must remove the transmission from the vehicle and split the case to access the 2094304054: MAIN SHAFT and shift rail assembly. Always replace the 0630513070: SNAP RING during reassembly.
Q: Is the 2094.306.004 compatible with the WG180 transmission?
A: While the fork is designed for WG100/WG130/WG131, it may physically fit WG180 units with the same 32 mm rail diameter. However, we recommend verifying your existing part number or consulting ZF’s technical documentation for exact cross-referencing.
