Overview
The ZF 6073.017.101 is a precision-engineered OEM genuine component specifically designed for the WG 190 Series transmission. This critical part functions as a hydraulic control element, regulating fluid pressure and flow within the valve body assembly to ensure precise clutch engagement and gear shifts. Positioned directly within the main control unit of the transmission, the SKU 6073.017.101 works in concert with the TRANSMISSION HOUSING to maintain structural integrity and fluid containment. Without this genuine part, the transmission cannot achieve the calibrated shift timing required for heavy-duty industrial applications.
Symptoms of Failure
- Delayed or harsh shifting: When the 6073.017.101 wears, hydraulic pressure drops, causing noticeable lag between gear changes or abrupt engagement that jolts the driveline.
- Internal fluid leakage: A worn sealing surface on this part allows transmission oil to bypass, leading to low fluid levels and eventual overheating of the HOUS.FRONT SECT.
- Erratic gear engagement: Operators may experience unexpected neutral conditions or failure to hold a selected gear under load, particularly during low-speed maneuvering.
- Contaminated hydraulic circuit: Degraded material from this component can shed debris into the oil, clogging downstream filters and damaging the HOUSING REAR PART.

Frequently Asked Questions
Q: How do I know if the 6073.017.101 is the correct part for my WG190 transmission?
A: Check the stamped identification plate on your transmission housing. The WG190 series will have a model code beginning with “WG190” followed by a three-digit variant number. The 6073.017.101 is used exclusively in valve body positions 3 and 4 of this series.
Q: Can I replace this part without removing the entire transmission?
A: Yes, in most cases the 6073.017.101 can be accessed by dropping the transmission oil pan and removing the valve body cover. However, you must also inspect the SCREEN SHEET for debris accumulation during this service.
Q: What torque specification should I use for the retaining bolts?
A: The CAP SCREW fasteners securing this component require 28 Nm (20.6 ft-lbs) of torque. Always use a calibrated torque wrench and apply thread locker to prevent loosening from vibration.
