ZF 6073.015.537 EST 37 A for WG210 | OEM Genuine Part

Overview

The ZF 6073.015.537 EST 37 A is a critical electro-hydraulic control unit designed specifically for the WG 210 Series transmission. This OEM genuine part regulates clutch pressure and shift timing, ensuring smooth gear engagement under heavy load conditions. Located within the valve body assembly, the SKU 6073.015.537 interfaces directly with the TRANSMISSION HOUSING to modulate hydraulic flow. Without this component, the transmission cannot execute commanded gear changes, making it essential for maintaining driveline integrity in commercial vehicles.

Symptoms of Failure

• Delayed or harsh shifting – Worn internal seals cause erratic clutch application, leading to jarring gear changes during acceleration.
• Transmission slipping under load – Inadequate pressure regulation results in momentary power loss when climbing grades or hauling heavy payloads.
• Erratic neutral-to-drive engagement – A failing EST 37 A produces a noticeable lag or shudder when shifting from park to drive.
• Hydraulic fluid contamination – Internal debris from degraded components bypasses the SCREEN SHEET, accelerating wear on adjacent parts.

Technical Specifications

Compatibility

This genuine ZF part is engineered for the WG 210 Series transmission family. It is directly compatible with WG180, WG200, and WG210 models used in medium-duty trucks and construction equipment. The unit mounts between the HOUS.FRONT SECT and the HOUSING REAR PART, requiring precise alignment during installation. For WG211 variants, verify the HOUSING REAR SECTION configuration before ordering.
