ZF 2094.298.042 HYDRAUL.CONTROL | OEM Genuine Part

Overview

The ZF 2094.298.042 HYDRAUL.CONTROL is a precision-engineered hydraulic control valve assembly that regulates oil flow and pressure within ZF power shift transmissions. Positioned internally between the torque converter and the clutch pack housing, this OEM genuine part (SKU: 2094.298.042) modulates hydraulic signals to engage and disengage gears smoothly. It interfaces directly with the 2094101012: TRANSMISSION HOUSING and the 2094301036: HOUSING, ensuring precise fluid routing for consistent shift quality under heavy loads in construction machinery.

Symptoms of Failure

• Delayed or harsh gear engagement — Worn internal spools or springs cause sluggish shifts or abrupt clunking when moving from neutral to drive.
• Intermittent transmission slipping under load — A failing hydraulic control unit cannot maintain clutch pressure, leading to power loss during grading or lifting operations.
• External oil seepage around the valve body — Cracks or degraded seals in the 2094.298.042 unit produce visible drips near the 2094301071: COVER interface.
• Erratic shift patterns or stuck gears — Contaminated hydraulic fluid or internal debris jams the control spool, causing the transmission to skip gears or remain locked in one range.

Technical Specifications

Compatibility

This hydraulic control unit is designed for ZF WG series transmissions commonly used in wheel loaders, graders, and telehandlers. It fits the following models (estimated based on valve body geometry and port configuration):

• ZF WG180 — All variants (WG180, WG180/II)
• ZF WG200 — Including WG200/II and WG200/III
• ZF WG210 — Select configurations with hydraulic shift control
• ZF 4WG-200 — Four-speed versions with torque converter lockup

Always verify the 2094298057: HOUSING compatibility before installation, as casting revisions may affect mounting bolt patterns.
