ZF 6073.015.208 EST 37 A for WG210 | OEM Genuine Part

Overview

The ZF 6073.015.208 EST 37 A is a critical electro-hydraulic control unit specifically designed for the WG 210 Series transmission. This genuine OEM part, identified by SKU 6073.015.208, governs the modulation of clutch pressure and shift timing within the transmission valve body. It directly interfaces with the transmission’s main housing to regulate hydraulic flow, ensuring precise gear engagement under load. When paired with a robust TRANSMISSION HOUSING, this component forms the core of the shift control system, translating electronic signals into mechanical actions that dictate transmission behavior.

Symptoms of Failure

• Erratic or harsh shifting under load: A failing EST 37 A often causes delayed or jarring gear changes, particularly when the transmission is hot, as internal solenoids lose calibration.
• Transmission slipping in higher gears: Worn seals within the unit can cause pressure loss, leading to a “slipping” sensation where engine RPM rises without proportional vehicle acceleration.
• Intermittent “limp mode” activation: Faulty electrical connections inside the 6073.015.208 trigger diagnostic trouble codes, forcing the transmission into a safe, low-power mode to prevent damage.
• Hydraulic fluid contamination: Internal degradation of the unit’s seals can introduce debris into the oil, often visible as metallic particles or a burnt odor in the fluid.

Technical Specifications

Compatibility

This genuine ZF part is engineered for the WG 210 Series transmission family. It is directly compatible with the WG180, WG200, and WG210 models used in heavy-duty commercial vehicles and off-highway machinery. The unit also integrates seamlessly with the HOUS.FRONT SECT and the HOUSING REAR PART to form a complete valve body assembly. For applications requiring a full rear section rebuild, pairing this part with the HOUSING REAR SECTION ensures proper alignment of internal oil galleries.
