Overview
The ZF 2095.246.026 PRESSURE PIN is a precision-machined component engineered for the hydraulic control systems within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part functions as a critical load-bearing element, transmitting precise hydraulic pressure to engage clutch packs and modulate gear shifts. Located within the valve body or clutch drum assembly, the pressure pin ensures consistent force application during torque transfer. The SKU 2095.246.026 is manufactured to exacting ZF tolerances, guaranteeing reliable operation under high-stress conditions. When paired with a properly functioning 5838109007: DIFFERENTIAL, this pin contributes to smooth power distribution across the drivetrain.
Symptoms of Failure
- Erratic or delayed gear engagement: A worn pressure pin fails to maintain consistent hydraulic pressure, causing hesitation when shifting between forward and reverse gears.
- Intermittent transmission slipping: As the pin loses its precise surface finish, hydraulic circuits may bleed pressure, leading to clutch pack slippage under load.
- Abnormal noise during acceleration: A deformed or pitted pressure pin can create metallic clicking or grinding sounds as it contacts the 0750117075: TAPER ROLLER BEARING surfaces within the housing.
- Hydraulic fluid contamination: Micro-fractures in the pin material can introduce metallic debris into the transmission fluid, visible as dark particles during oil changes.

Compatibility
This pressure pin is specifically designed for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It is also compatible with select WG180 and WG200 variants that share the same hydraulic control architecture. The pin interfaces directly with the 2095209019: DIFFERENTIAL assembly and is secured using the 0631329086: SPRING PIN for retention. Always verify your transmission’s serial number against ZF documentation before installation.
