Automatic Transmission Fluid (ATF) is a critical fluid for lubricating your car's transmission. Selection of the correct type is essential to the smooth operation and durability of the modern automatic transmission. While early designs of self-shifting transmissions provided 3 or 4 gear ratios, modern computer-controlled versions offer 6 or more output speeds, greatly improving driveability and fuel efficiency.
As transmissions have become more sophisticated, advanced technology fluids are required to ensure continuous smooth shifting under all driving conditions. Adding further to the complexity of ATFs has been the rapid emergence of different technologies, the Continuously Variable Transmission (CVT) and Dual Clutch Transmission (DCT), which require their own specialised fluids.
With Castrol's wide range of Automatic Transmission Fluids you can be confident of finding the right ATF for your vehicle. With over 100 years of experience in developing transmission fluids and being the choice of many leading car manufacturers for factory-fill products, you can be sure that Castrol ATF will give a smoother drive for longer.
As part of a global simplification program, Castrol’s entire driveline range is now unified under the Castrol TRANSMAX brand.The advanced Castrol TRANSMAX range features Smooth Drive Technology™ with active control molecules that automatically adjust their friction level with changing pressures and speed. This ensures the transmission is constantly served the right level of friction at any given moment – protecting the parts and delivering a smoother drive for longer. That’s why, 2 out of every 3 major vehicle manufacturers** choose Castrol transmission fluids as part of their factory fill.
