Overview
This OEM genuine ZF 6009.092.314 component is a critical internal actuator or valve assembly designed specifically for the WG 160 series transmission. Positioned within the hydraulic control unit, this part modulates oil flow to engage clutch packs and manage gear shifts under load. The SKU 6009.092.314 ensures precise pilot pressure regulation, directly influencing shift quality and torque converter lockup. When paired with a robust TRANSMISSION HOUSING, this genuine part maintains the sealed hydraulic circuit required for consistent performance in heavy-duty applications.
Symptoms of Failure
- Erratic or delayed gear engagement – Worn internal seals cause pressure loss, leading to harsh or delayed shifts when accelerating from a stop.
- Transmission fluid leaks near the valve body – Degraded O-rings or cracked bores in the 6009.092.314 assembly allow ATF to seep past, leaving puddles under the bell housing.
- Slipping under load on inclines – Inadequate clamping force from a failing actuator results in clutch pack slip during uphill hauling or heavy towing.
- Intermittent neutral condition – A stuck spool within this part can cause the transmission to drop into neutral without warning, especially after prolonged highway driving.

Compatibility
While primarily engineered for the WG 160 transmission, the 6009.092.314 actuator is also compatible with select ZF models that share the same hydraulic architecture. It fits the WG 180 and WG 200 series when used with the correct HOUS.FRONT SECT and HOUSING REAR PART. For WG 210 variants, verify the bore alignment against the HOUSING REAR PART to ensure proper sealing. This part is not backward-compatible with older WG 150 units without adapter plates.

Frequently Asked Questions
Q: Can the 6009.092.314 be rebuilt with aftermarket seals?
A: ZF does not supply separate seal kits for this part. We recommend replacing the entire OEM unit to avoid bore wear mismatches that cause recurrent leaks.
Q: Will a failing 6009.092.314 trigger diagnostic trouble codes?
A: Yes. Most WG 160 electronic controllers log a P0741 or P0743 code when this actuator fails, indicating pressure regulation faults in the lockup circuit.
Q: How does this part interact with the transmission housing?
A: The 6009.092.314 seats directly into a machined bore in the TRANSMISSION HOUSING. Any scoring on that bore surface will compromise the seal, so always inspect both components during replacement.
