C-3: Older specification for automatic transmissions of heavy vehicles, which has now been replaced in most applications by C-4.
C-4: The most widely used specification for automatic transmissions, torque converters, and hydraulic systems in heavy vehicles and earthmoving machinery.
TES-295: Fully synthetic ATF fluid, specially approved for modern Allison transmissions with requirements for exceptionally long change intervals (Long Life).
TES-389: Automatic transmission fluid (based on Dexron III properties), designed for Allison professional equipment that follows regular maintenance intervals
Viscosity: It reveals how viscous a lubricant is. It is determined by 2 numbers. The first one with the letter "W" (Winter) refers to how the oil flows when it is cold. The second one refers to how the oil flows when it is hot under operating conditions of the vehicle.
Differentials: Lubricants enhanced with extreme pressure (EP) additives, essential for protecting hypoid gears that are subjected to heavy loads. They ensure smooth power transmission to the wheels without wear and overheating.
Dual Clutch Transmissions (DCT / DSG): Specialized dual-action fluids. They protect the gears from wear, while also functioning as hydraulic fluids for fast gear shifts, simultaneously cooling the sensitive multi-plate clutches to prevent slippage.
