Lubrication plays a vital role in the transmission, to protect the numerous finely engineered, precision parts, as it is a complex and expensive unit to repair or replace.
The electro-hydraulic system, a Haldex coupling, commonly used in VAG, Ford & Volvo, is attached to the rear differential and enables the vehicle to switch between front an all-wheel drive. Sensors detect wheel slip and then engages clutch plates within the coupling, which engages the rear differential to provide AWD. This creates a high degree of friction and degrades the metallic components within the system over time. Replacing the filter within this system at the recommended service intervals helps to prolong the system.
Febi has a comprehensive range of both ATF and Haldex service kits, containing all the necessary components required for a complete oil change – transmission oil, a filter, seals and installation instructions.
