DCTfluid

DCTfluid is a class of lubricants designed for dual-clutch transmissions (DCTs), including both wet- and dry-clutch configurations. These fluids are formulated to meet the unique demands of rapid gear changes, high shear, and varying temperatures encountered in modern DCT systems. They aim to provide smooth clutch engagement, reliable wear protection, and resistance to foaming and oxidation.

Typical composition and properties of DCTfluid include synthetic base oils, such as PAO or ester blends, combined with additives that improve friction control, anti-wear performance, detergency, corrosion inhibition, and oxidation resistance. The fluids are engineered to maintain stable viscosity across a broad temperature range and to resist shear-induced viscosity loss, helping to preserve shifting quality and transmission efficiency over time.

Applications and compatibility considerations vary by transmission design and manufacturer specifications. DCTfluid is recommended for use in transmissions explicitly listed by the vehicle or transmission maker. Using a fluid outside the recommended specification can lead to suboptimal shifting, clutch wear, or other transmission issues. Compatibility with both wet and dry clutch systems depends on the particular formulation and additive package.

Maintenance and handling guidelines emphasize proper fluid change intervals as specified by the vehicle manufacturer, cleanliness of the fluid during replacement, and adherence to safety data for handling and disposal. As with other specialized transmission fluids, selection should follow the OEM or authoritative industry guidelines to ensure optimal performance and warranty compliance.
