ZF 6073.015.550 EST 37 A for WG210 | OEM Genuine Part

Overview

The ZF 6073.015.550 EST 37 A is a genuine OEM solenoid valve assembly engineered specifically for the WG 210 series transmission. This electro-hydraulic component modulates oil flow to control clutch engagement and shift timing within the valve body. As a critical actuator, the SKU 6073.015.550 ensures precise pressure regulation, directly influencing gear change smoothness and overall drivetrain efficiency. It sits within the transmission’s hydraulic control unit, interfacing with the TRANSMISSION HOUSING to maintain consistent fluid routing.

Symptoms of Failure

• Erratic or delayed shifting: When the EST 37 A solenoid fails, you may experience hesitation between gears, especially during acceleration or under load, as hydraulic pressure becomes inconsistent.
• Harsh engagement or slipping: A worn valve can cause abrupt clutch application or a sensation of the transmission slipping out of gear, often accompanied by fluctuating RPMs.
• Transmission fluid leaks: Degraded seals on the 6073.015.550 unit allow ATF to seep past the solenoid body, leaving visible drips near the valve body or HOUS.FRONT SECT interface.
• Check engine or transmission warning lights: Modern ZF systems log fault codes for solenoid circuit malfunctions, triggering dashboard alerts and potentially limiting gear selection.

Technical Specifications

Compatibility

This solenoid is primarily designed for the ZF WG 210 series, but it also fits select models in the WG 180, WG 200, and WG 220 families due to shared valve body architecture. It is commonly used in off-highway vehicles, construction equipment, and heavy-duty trucks. For proper installation, ensure the HOUSING REAR PART and HOUSING REAR SECTION are free of debris to avoid contaminating the solenoid bore.
