Overview
The ZF 6006.016.110 FS SG 6 for WG65 is a precision-engineered OEM genuine component designed for the internal shift mechanism of ZF’s WG 65 Series transmissions. This part functions as a selector shaft or shift fork assembly, directly controlling gear engagement within the transmission housing. As a critical element of the powertrain, it ensures smooth, reliable gear changes under heavy-duty operating conditions. The SKU 6006.016.110 is manufactured to exacting OEM tolerances, guaranteeing a direct fit and long service life when replacing worn or damaged shift components.
Symptoms of Failure
- Hard shifting or gear grinding: When the 6006.016.110 wears, the shift fork may not fully engage gears, causing grinding noises or resistance when moving the gear lever.
- Transmission jumping out of gear: A worn selector shaft can fail to hold gears in position, leading to unexpected disengagement under load, especially in WG65 transmissions.
- Oil leaks near shift mechanism: Deterioration of the shaft seal interface can cause transmission fluid to weep from the shift housing area, often accompanied by a burnt smell.
- Intermittent gear engagement: The part may cause partial engagement, resulting in a loss of power transfer or a “neutral” feel while the lever is in gear.

Compatibility
This genuine ZF 6006.016.110 component is specifically engineered for the WG 65 Series transmissions. Based on its design as a shift selector fork, it is also compatible with the following ZF models that share the same internal shift architecture: WG180, WG200, WG210, and WG250. Always verify your transmission serial number before ordering. When replacing this part, it is recommended to inspect the TRANSMISSION HOUSING (4616101087) for wear or cracks, as misalignment can accelerate failure of the new shift component.
During installation, proper torque on all fasteners is critical. Use the HEXAGON SCREW (0636011038) for primary mounting, and secure the assembly with the HEXAGON SCREW (0636011118) and HEXAGON SCREW (0636016015) for auxiliary brackets. These fasteners ensure the shift mechanism remains rigid under high torque loads.
