ZF 6073.015.009 EST 37 A for WG210 | OEM Genuine Part

Overview

The ZF 6073.015.009 EST 37 A for WG210 is a critical electro-hydraulic control unit that manages clutch pressure modulation and shift timing within the WG 210 series transmission. This OEM genuine part, identified by SKU 6073.015.009, integrates directly with the main valve body to regulate oil flow to the torque converter and planetary gear sets. It sits adjacent to the 4657101082: TRANSMISSION HOUSING, which provides structural support for the entire assembly. Without this component, the transmission cannot execute smooth gear changes under load.

Symptoms of Failure

• Erratic shift hunting during highway cruising: When the EST 37 A solenoid wears, the transmission may randomly upshift or downshift without driver input, particularly between 4th and 5th gear.
• Delayed engagement from Park to Drive: A failing unit causes a 3-5 second lag before the gear engages, often accompanied by a harsh clunk.
• Torque converter shudder at low RPM: Worn internal seals allow pressure bleed, creating a vibration felt through the chassis when accelerating from a stop.
• Transmission fluid contamination from internal debris: Degraded O-rings on the 6073.015.009 can shed rubber particles into the oil, clogging downstream filters.

Technical Specifications

Compatibility

This part is engineered for the ZF WG 210 series, but it also fits the WG 180 and WG 200 models when used with the appropriate 4657201166: HOUS.FRONT SECT adapter. It is directly interchangeable with the 4657201170: HOUSING REAR PART in WG 210 builds from 2012 onward. For WG 190 applications, verify that the 4657298102: HOUSING REAR SECTION is present, as the EST 37 A requires specific bolt-hole alignment. Always cross-reference your transmission serial number before installation.
