Overview
The ZF 6073.015.015 is a precision-engineered OEM genuine part designed specifically for the WG 160 Series transmission. This component serves as a critical interface within the hydraulic control system, regulating fluid flow and pressure to ensure smooth gear engagement. As a direct replacement for the original factory unit, the SKU 6073.015.015 guarantees exact fitment and performance. It sits in the valve body assembly, directly interacting with the TRANSMISSION HOUSING to maintain proper oil circulation and prevent internal cross-leakage.
Symptoms of Failure
- Delayed or harsh shifting: When the 6073.015.015 wears, hydraulic pressure drops, causing noticeable lag between gear changes or abrupt engagement.
- Transmission fluid leaks: Degraded seals on this part allow oil to escape around the HOUS.FRONT SECT interface, leaving puddles under the vehicle.
- Intermittent gear slipping: Worn internal passages fail to hold pressure, causing the transmission to momentarily lose drive power under load.
- Overheating transmission: Restricted fluid flow from a failing unit forces the system to run hotter than normal, triggering warning lights.

Frequently Asked Questions
Q: How do I know if the 6073.015.015 is failing?
A: Watch for delayed engagement when shifting from neutral to drive, or visible oil residue around the valve body area. A transmission that whines under load also indicates this part may be compromised.
Q: Can I install this part without removing the transmission?
A: In most WG 160 applications, the 6073.015.015 is accessible after dropping the transmission pan and removing the valve body. However, always consult the service manual for your specific chassis configuration.
Q: Is this part interchangeable with aftermarket versions?
A: Only OEM genuine ZF parts like the 6073.015.015 guarantee the exact internal tolerances required for WG 160 series operation. Aftermarket copies often cause pressure irregularities and premature wear.
