Superior high temperature protection to effectively resist oxidation.Enhanced friction durability for smooth transmission performance.Low viscosity formula for maximum fuel efficiency in modern automatic transmissions.OEM approved and licensed by Ford (MERCON® LV) and GM (DEXRON®-VI).Smooth Drive Technology™: Several Castrol Transmax products are formulated with Smooth Drive Technology™, which are active control molecules that automatically adjust their friction level under changing pressures and speed – delivering a smoother drive for longer. The Castrol® Transmax portfolio contains a broad range of automatic transmission fluids liquid engineered to protect critical transmission components, including products that have been licensed by GM, Ford and Chrysler as well as fluids that meet the JASO requirements of popular Japanese imports from Toyota, Honda and Nissan. So using the right ATF is critical to the performance and long life of your transmission. The ATF precisely controls friction in the clutch packs and maintains it throughout the drain interval … which is perhaps the most important property of an ATF all while providing lubrication to hundreds of moving parts even under high temperatures and extreme pressure. It has to flow easily from minus 40 degrees Fahrenheit to nearly 400, even in fine valve assemblies. It acts as a corrosion inhibitor and wear protection for the Planetary Gear sets. It acts as a hydraulic fluid, to engage clutch packs & shift the gears. The one component of the entire system that’s critical to all of these parts working properly together is the Automatic Transmission Fluid, or ATF. Finally, the Mechatronics is the “brain” of the transmission, a complex system of ports, valves and electronics that control all transmission functions. It uses two turbines which spin independently, but which are fluid coupled allowing the engine to idle while the engine is stopped and produce smoother acceleration as it shifts through the gears. The Torque Converter connects the transmission to the engine and multiplies the torque during initial acceleration. Clutches or “clutch packs” engage and disengage the gear sets. The planetary gear sets provide the chosen gear ratios for the vehicle.
The pump supplies pressurized transmission fluid for many uses throughout the unit. There are several main components that make up the step-type transmission. The Dual Clutch Transmission (or DCT), the Continuously Variable Transmission (or CVT) and the step-type transmission which is the most common, especially here in the US. There are 3 basic types of automatic transmissions found throughout the world. The automatic transmission combines electrical & mechanical systems, hydraulics and computer processors to smoothly shift through the gears and transfer engine power to the drive wheels.
In fact, the automatic transmission is perhaps the most complicated mechanical component in an automobile. Automatic transmissions are now more complex than ever, placing ever-greater demands on auto transmission fluids.
