Overview
The ZF 4108.014.014 P 3300 is a high-pressure hydraulic pump cartridge, an OEM genuine component engineered for the internal lubrication and control circuits of heavy-duty ZF transmissions. This part serves as the core rotating assembly within the transmission’s main oil pump, responsible for generating the precise hydraulic flow required for clutch engagement, torque converter charging, and gear shift actuation. Designated by SKU 4108.014.014, this unit is a direct replacement for the original factory-installed cartridge, ensuring that the transmission’s hydraulic system maintains its designed pressure and volume. It sits directly within the pump housing, typically mounted on the transmission’s rear cover or PTO drive pad, and is critical for converting mechanical rotation into hydraulic energy.
Symptoms of Failure
When the ZF 4108.014.014 cartridge begins to degrade, operators will notice distinct operational issues. Identifying these early can prevent catastrophic transmission damage.
- Erratic or delayed gear engagement: The transmission hesitates or slams into gear, especially when cold, due to insufficient hydraulic pressure from a worn pump cartridge.
- Low transmission oil pressure warning: A persistent dashboard or diagnostic code indicating low line pressure, often accompanied by a whining noise from the pump area.
- Torque converter shudder or slip: A vibration or loss of power under load, particularly at low speeds, as the converter fails to receive adequate charging oil flow.
- Visible metallic debris in the oil pan: During routine oil changes, finding fine bronze or steel particles indicates the cartridge’s internal gears or bushings are wearing out.

Compatibility
This OEM genuine cartridge is designed for integration into ZF’s modular transmission families that utilize a separate, serviceable pump cartridge. Based on the part type and OEM reference, the 4108.014.014 is compatible with the following ZF transmission models:
- ZF WG180 series (all variants)
- ZF WG200 series (including WG200-1, WG200-2)
- ZF Ecomat 4HP and 5HP series (specific hydraulic pump variants)
- ZF Ergopower series (early generation models)
Note: Always verify the pump housing casting number and transmission serial number to ensure correct fitment, as some models use a different displacement cartridge.
