Dual-clutch transmissions (DCT) combine the performance benefits of manual transmissions with the smooth transitions and ease-of-use that automatic transmissions provide. They are frequently used in high-performance vehicles where their performance benefits come most into play.

Automatic and Dual-Clutch Transmissions

Traditional automatic transmissions have a defined set of planetary gears that engage based on vehicle speed. The correct gear is selected as the vehicle accelerates and decelerates.

Cutaway of a Dual-Clutch Transmission.

DCTs are automatic transmissions based on the architecture of manual transmissions. The design is often comprised of two manual transmissions in the same housing.  Most rely on computer-controlled, wet multi-plate clutches and do not require torque converters.

Dual-clutch transmissions provide more-efficient shifts than traditional automatics because, as one clutch is engaged, the other clutch readies the next gear.

If properly maintained and lubricated, the system delivers smooth, split-second shifts, the perfect complement to a powerful, high-performance engine.

While DCTs are capable of seamless shifts, they can suffer from shudder at low-speeds and during sustained acceleration. A transmission fluid that allows too much or too little friction can result in shudder, slipping or clashing.

DCT fluid must also maintain the proper viscosity to provide protection during the high-heat operation native to high-performance sports sedans and super cars.

AMSOIL 100% Synthetic DCT Fluid

AMSOIL 100% Synthetic DCT Fluid is specifically engineered for sophisticated dual-clutch transmissions. Its perfectly balanced frictional properties protect against shudder and clashing to consistently produce fast, smooth shifts. AMSOIL DCT Fluid provides exceptional durability and stability in stop-and-go traffic, and excels under intense, high-heat conditions. It promotes stable synchronizer engagements and extending the life of the transmission.

  • Outstanding wear protection
  • Excellent performance in extreme heat and cold
  • Designed to prevent shudder
