There is no standard color for CVT fluid, however Castrol Transmax CVT Fluid is red. A CVT-specific fluid should always be used to ensure proper performance and protection. Hybrid vehicles are commonly equipped with CVTs and they are occasionally used in non-hybrids. Low temperature flow to ensure effective operation of hydraulics and electronics controls at low temperatureĬontinuously Variable Transmissions (CVTs)ĬVTs have continuously changing speed ratios unlike typical automatic transmissions which have distinct gear shifts.Viscosity stability or proper fluid thickness over a wide temperature range.Extreme pressure/load carrying performance to ensure anti-wear and gear durability.Frictional characteristics to enable smooth gear changes by supplying the correct friction to the transmission clutches and bands.Heat resistance and thermal stability to help prevent deposit and sludge from forming due to high temperatures.Additionally, anti-wear and load carrying components in the transmission fluid must ensure long synchronizer life and gear protection. Manual transmission fluid, like engine oil, is generally brown to amber in color.Ĭritical areas of ATF performance include: The transmission synchronizer must engage smoothly for proper shift performance. Key performance and protection requirements for manual transmissions include synchronizer compatibility, durability and shift quality. Manual transmission fluid (MTF) – protection and operation

Transmissions require distinct fluids for best performance depending on the vehicle make, model and year.
#Automatic transmission driver#
In the US, most passenger cars have an automatic transmission, which means the transmission changes gears as required automatically - the driver does not need to take any action. Manual transmissions, on the other hand, are dependent on the operation of the clutch and shifter by the driver each time a gear shift is required. Automatic transmission fluid is distinctly different from transmission fluid made for manual transmissions.
