Overview
The ZF 6073.017.260 is a precision-engineered OEM genuine component designed specifically for the WG 190 series transmission. This part functions as a critical interface within the hydraulic control system, regulating fluid flow and pressure to ensure smooth gear engagement and torque converter lock-up. Positioned within the valve body assembly, the SKU 6073.017.260 directly influences shift quality and overall drivetrain efficiency. As an OEM genuine part, it guarantees exact fitment and factory-specified performance, eliminating the variability found in aftermarket alternatives.
Symptoms of Failure
When the ZF 6073.017.260 begins to wear, operators often notice delayed or harsh shifting between gears, particularly under load. A second common failure symptom is intermittent transmission slipping during acceleration, which can be mistaken for low fluid levels. You may also observe erratic shift patterns or the transmission failing to engage the correct gear ratio. Finally, internal fluid leaks around the valve body area can occur, leading to low hydraulic pressure and eventual transmission overheating if left unaddressed.

Frequently Asked Questions
Q: Can I install the 6073.017.260 without replacing the housing gaskets?
A: It is strongly recommended to replace all sealing surfaces, including the TRANSMISSION HOUSING gasket, whenever this component is serviced. Reusing old gaskets can lead to fluid leaks and pressure loss.
Q: How do I know if my WG 190 transmission needs this specific part?
A: If you are experiencing erratic shifting or slipping in 3rd and 4th gears, the 6073.017.260 is a common culprit. A diagnostic pressure test of the valve body will confirm if this component is worn.
Q: Is this part interchangeable with the WG 200 series?
A: Yes, the 6073.017.260 is physically identical to the part used in WG 200 transmissions. However, always cross-reference your transmission serial number to ensure the valve body calibration matches.
