AMSOIL 100% Synthetic DCT Fluid is a purpose-built transmission fluid engineered to deliver fast, smooth shifts and reliable wear protection in dual-clutch transmissions found in performance sports sedans, supercars, and everyday vehicles equipped with DCT technology.
Dual-clutch transmissions are fundamentally different from conventional automatics. They operate as two manual transmissions sharing a single housing, with one clutch engaged while the other pre-selects the next gear. This architecture demands a fluid that can simultaneously manage clutch friction, protect gear teeth under extreme pressure, and maintain stable viscosity across a wide temperature range. Using a generic ATF or the wrong specification can lead to shudder, rough shifts, and premature component wear.
ENGINEERED TO PREVENT SHUDDER
DCTs are prone to shudder and lurching at low speeds, particularly in stop-and-go traffic where clutch engagement cycles are frequent and heat builds rapidly. AMSOIL Synthetic DCT Fluid is formulated with friction modifiers specifically calibrated for dual-clutch applications. It promotes stable synchronizer engagements that reduce the jerky, inconsistent shifts common in vehicles like the Ford Focus with its DPS6 transmission, the VW Golf DSG, and BMW M cars running DCT units. Verified buyers running this fluid in C8 Corvettes and Mustangs consistently report noticeably smoother shift quality after a fluid swap.
OUTSTANDING WEAR PROTECTION UNDER EXTREME PRESSURE
The gear sets inside a DCT see enormous contact pressures, especially in high-horsepower, high-torque applications like the Porsche 911 PDK or Nissan GT-R. AMSOIL Synthetic DCT Fluid combines high film strength with anti-wear and extreme-pressure additives designed specifically for the metal-on-metal contact surfaces in these transmissions. In Four-Ball Wear Testing per ASTM D4172B (40 kg, 75°C, 1200 rpm, 1 hour), the fluid produced a wear scar of just 0.41 mm. That translates to real protection for gears, bearings, and synchronizers over the full service interval.
RESISTS HEAT AND OXIDATION IN HIGH-TEMPERATURE DCTs
DCTs in performance vehicles like the Ferrari 488, McLaren 720S, and Mercedes-AMG GT generate significant heat, particularly during spirited driving or track use. AMSOIL Synthetic DCT Fluid has a flash point of 230°C (446°F) and a fire point of 244°C (471°F) per ASTM D92, giving it substantial thermal headroom. A viscosity index of 171 means the fluid maintains its protective film across a wide operating range without thinning out under heat or thickening excessively in cold conditions.
SUPERIOR SHEAR STABILITY FOR CONSISTENT VISCOSITY
Transmission fluid degrades over time as the molecular structure breaks down between meshing gear teeth. This mechanical shearing reduces viscosity and compromises protection. AMSOIL Synthetic DCT Fluid resists shear to maintain consistent viscosity throughout its service life. With a kinematic viscosity of 7.7 cSt at 100°C and 38.8 cSt at 40°C (ASTM D445), the fluid sits squarely in the range demanded by major DCT manufacturers. A Brookfield viscosity of 8,822 cP at -40°C (ASTM D2983) confirms reliable cold-temperature flow, which matters for cold-start protection in climates where temperatures drop well below freezing.
EXTREME COLD-TEMPERATURE PERFORMANCE
A pour point of -58°C (-72°F) per ASTM D97 means this fluid remains pumpable in conditions far beyond what most drivers will ever encounter. For owners of VW and Audi vehicles with DSG transmissions in northern climates, or BMW owners concerned about cold-weather shift quality, that margin provides real assurance that the fluid will flow and protect from the moment the transmission is engaged.
