This product has been exclusively designed for Harley-Davidson® and is the only synthetic product tested and certified by Harley-Davidson® engineering for use in H-D®/Buell® motorcycles. However, Harley-Davidson®, in close partnership with our suppliers, analyzed available petrochemical technology and developed a custom-blended candidate fluid that can be used in all three cavities of a Harley-Davidson®/Buell® motorcycle. Why is H-D® introducing a synthetic now?īecause Harley-Davidson® cannot test and certify all available synthetics on the market nor control their oil and additive formulations, we have discouraged their use. In the past, Harley-Davidson® did not recommend the use of synthetic oils in H-D®/Buell® motorcycles. Provides high temperature film strength, which means the lubricant maintains film thickness in high power output and high engine speed conditions, keeping the metal parts from rubbing against each other and resulting in less wear. Is formulated for reduced oil consumption, improved wear protection, high temperature detergency, and superior overall field performance. Offers improved film strength for superior wear protection at high temperature, and improved deposit control for a cleaner engine, transmission, and primary chain case. SYN3® Can be used in the engine, primary chain case, and transmission. SERVICE APPOINTMENT What are the key benefits to using SYN3®? 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.Screamin' Eagle® SYN3® Synthetic Motorcycle Lubricant 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. What kind of automatic transmissions are there? Shift through the gears and transfer engine power to the drive wheels.

The automatic transmission combines electrical & mechanical systems, hydraulics and computer processors to smoothly In fact, the automatic transmission is perhaps the most complicated mechanical component in an automobile. ATF fluids engineered to exceed SpecificationsĪutomatic transmissions are now more complex than ever, placing ever-greater demands on auto transmission fluids.
