New Synthetic DCT Fluid Rounds Out AMSOIL Transmission Fluid Family.

AMSOIL DCT Dual-Clutch Transmission

The concept of two transmissions working in tandem within one vehicle dates back to the 1930s. The dual-clutch transmission (DCT) made its first practical appearance decades later in several 1980s-era race cars. In 2003, Volkswagen’s Golf* Mk4 R32 was the first production vehicle to feature the technology. Today the spectrum of vehicles with DCTs has widened, from the Hyundai Sonata* to the Nissan GT-R*.

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. DCTs are automatic transmissions based on the architecture of manual transmissions. They consist of two manual transmissions in the same housing.  Most rely on computer-controlled, wet multi-plate clutches and do not require torque converters. DCTs provide more efficient shifts than traditional automatics because as one clutch is engaged the other readies the next gear. 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. Synthetic DCT Fluid’s exceptional durability provides stability in stop-and-go traffic and excels under intense, high-heat conditions. It promotes stable synchronizer engagements, extending the life of the transmission.
