ZF 2095.306.023 GEARSHIFT SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.306.023 GEARSHIFT SHAFT is a precision-machined component designed for the internal shift rail assembly within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part, identified by SKU 2095.306.023, directly controls the engagement and disengagement of gear sets by transferring linear motion from the shift fork to the synchronizer hub. Located in the upper valve body or shift housing, it ensures precise gear selection under high-torque conditions. When paired with a properly functioning 5838109007: DIFFERENTIAL, this shaft maintains consistent power flow through the drivetrain.

Symptoms of Failure

• Hard shifting or gear lockout: A worn or bent gearshift shaft prevents smooth engagement, causing the operator to force the lever or experience complete inability to select a gear.
• Intermittent gear slipping under load: When the shaft’s detent grooves wear, the shift fork cannot hold the gear in position, leading to sudden disengagement during acceleration.
• Metallic grinding noise from transmission housing: Excessive play in the shaft allows the shift fork to contact rotating clutch packs, producing a distinct grinding sound that worsens with RPM.
• Oil contamination from metal debris: Fractured shaft surfaces shed fine metallic particles into the transmission fluid, often visible during drain intervals as silver or bronze sludge.

Technical Specifications

Compatibility

This gearshift shaft is engineered for ZF WG-series transmissions with a 6-speed countershaft layout. It is a direct fit for the following models: WG100, WG130, and WG131. While primarily designed for these units, it may also be compatible with WG180 and WG200 variants when used in the auxiliary shift rail position. Always verify the shift fork interface geometry before installation. For optimal performance, inspect the mating 0750117075: TAPER ROLLER BEARING and the 2095209019: DIFFERENTIAL assembly during service. The shaft also requires a 0631329086: SPRING PIN for proper retention in the shift housing.
