Overview
The ZF 2094.147.407 OIL SUPPLY is a critical hydraulic component engineered to regulate and direct pressurized lubrication oil within ZF heavy-duty transmissions. This OEM genuine part ensures consistent oil flow to bearings, gears, and clutch packs, preventing thermal damage and mechanical wear. As a dedicated oil supply unit, it sits directly within the transmission valve body or pump housing, acting as the primary conduit for fluid distribution. The SKU 2094.147.407 is precision-machined to factory tolerances, guaranteeing seamless integration with your existing assembly. Without this part, the transmission cannot maintain proper hydraulic pressure, leading to rapid component degradation.
Symptoms of Failure
When the ZF 2094.147.407 OIL SUPPLY begins to fail, operators typically notice these specific warning signs:
- Intermittent gear slipping under load – A worn oil supply unit cannot maintain consistent hydraulic pressure, causing clutches to disengage momentarily during heavy operation.
- Visible oil leaks around the transmission housing – Cracks or seal degradation in the oil supply body allow pressurized fluid to escape, often pooling beneath the vehicle.
- Delayed engagement or harsh shifting – Reduced oil flow leads to sluggish clutch pack actuation, resulting in jarring gear changes or hesitation when shifting from neutral to drive.
- Overheating transmission fluid – Inadequate lubrication causes friction surfaces to generate excessive heat, triggering warning lights or burnt fluid odor.

It is installed directly against the 2094101011: TRANSMISSION HOUSING, which provides structural support and fluid routing channels. The oil supply unit is sealed using a 0635460022: BALL check valve to prevent backflow, while the 2094301045: HOUSING encloses the internal passages. A 2094301044: COVER protects the assembly from debris ingress. Always verify your transmission serial number before ordering.
