Ensuring your vehicle's dual-clutch transmission (DCT) operates smoothly relies heavily on the quality of the fluid it uses. Like other transmission fluids, the frictional properties and durability of DCT fluid are paramount. Opting for a high-quality DCT fluid helps prevent issues such as shuddering, slipping, or clashing during low-speed maneuvers and sustained acceleration.

Unlike traditional automatic transmissions, which rely on a set of planetary gears and a torque converter to manage gear engagement, DCTs follow a different design paradigm. DCTs are essentially a blend of manual and automatic transmissions, housing two manual transmissions within the same unit. Instead of a torque converter, DCTs employ two automated clutches to connect the engine to the transmission. This setup enables faster shifts compared to traditional automatics. As one clutch engages, the other prepares the next gear, resulting in seamless, split-second gear changes. These rapid shifts optimize power transfer to the wheels, enhancing efficiency and performance.

AMSOIL advises adhering to the drain interval specified by your vehicle's manufacturer. Drain intervals can vary between manufacturers, with some recommending changes as frequently as every 30,000 miles. To ensure optimal performance and longevity of your transmission, consult your vehicle owner’s manual for manufacturer-specific recommendations.
