Transmission Filters for DAF Trucks

The transmission filter on a DAF truck removes wear particles and contamination from the gearbox oil before they circulate to bearings, synchronisers and clutch packs. A clean oil circuit is essential for smooth gear selection, particularly in automated gearboxes where the hydraulic control system operates at high precision. Truckstop stocks transmission filters for DAF XF, CF and LF models in OE-quality specification.

When to Replace the DAF Transmission Filter

Transmission filter replacement intervals are specified in the DAF service schedule, typically aligned with transmission oil change points. Automated gearboxes such as the ZF AS-Tronic fitted to the DAF XF are particularly sensitive to oil contamination; replacement at the scheduled interval is important to maintain hydraulic control system performance. On high-mileage vehicles, reduced shift quality or hesitation may indicate the filter is due for replacement ahead of schedule.

How do I find the correct transmission filter for my DAF?

The model series and transmission type are the key details. DAF XF, CF and LF trucks have been fitted with different transmission types across their production history, and filter specifications vary by gearbox. Truckstop lists filters by vehicle and transmission application. Contact the trade team with the chassis number or gearbox type if the correct filter is not shown.

What is the effect of a blocked transmission filter on gearbox performance?

A blocked transmission filter restricts oil flow within the gearbox, which reduces the hydraulic pressure available for gear selection in automated boxes. This can cause slow or hesitant gear changes, transmission warning lights and, in advanced cases, protection mode activation where the gearbox limits available gear selections. Replacing the filter and fluid at the scheduled interval prevents these issues.

Should the transmission oil and filter be replaced together on a DAF truck?

Yes. Replacing the transmission filter without changing the oil leaves contaminated fluid in the system, and changing the oil without replacing the filter means the new oil is immediately filtered through a blocked or near-capacity element. Both should be replaced together at the scheduled service point for the change to be effective.
