Overview
The ZF 2094.340.007 LIFTING SHAFT (SKU: 2094.340.007) is a critical actuation component within the WG100, WG130, and WG131 transmission series. This genuine OEM part serves as the mechanical interface that translates shift-fork movement into precise gear engagement. Positioned inside the main transmission housing, the lifting shaft rotates to lift and lower selector forks, ensuring smooth ratio changes under load. As a wear-prone element in high-cycle applications, replacing this shaft with the OEM-specified 2094.340.007 restores original shift feel and prevents internal damage to adjacent components like the 2094101011: TRANSMISSION HOUSING.
Symptoms of Failure
- Hard shifting or gear lockout: A worn lifting shaft causes binding in the selector mechanism, making it difficult to engage or disengage gears, especially under torque.
- Metallic grinding noise from transmission: Excessive play in the shaft leads to misalignment of shift forks, producing a grinding sound during gear changes.
- Oil leaks around shift cover area: A damaged shaft can compromise the seal surface, allowing transmission fluid to weep past the 0635460022: BALL and cover interface.
- Intermittent gear slipping: When the lifting shaft fails to fully rotate, shift forks do not complete their travel, resulting in partial gear engagement and power loss.

Compatibility
This genuine lifting shaft is engineered specifically for ZF WG100, WG130, and WG131 transmission models. It is not interchangeable with WG180 or WG200 series units due to differing shift-rail geometry. For proper installation, always pair this shaft with a new 2094301045: HOUSING and 2094301044: COVER to maintain precise tolerances. Verify your transmission model number before ordering.
