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-shiting 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.
