\"\"Signature Series 100% Synthetic Automatic Transmission Fluid<\/span><\/a><\/p>\n

\n

Proven in 180,000-mile, Severe-Service Taxi Fleet Field Trial<\/strong>
To demonstrate its effectiveness in severe service, Signature Series Multi-Vehicle Synthetic ATF was installed in Las Vegas taxi cabs. The vehicles routinely encountered demanding stop-and-go driving loaded with passengers and cargo, while the desert environment presented extremely hot ambient temperatures, placing enormous strain on the fluid. Following 180,000 miles, a transmission was selected for analysis. The Aluminum Beaker Oxidation Test (ABOT) is an industry standardized test used to determine a transmission fluid’s oxidation resistance, which is a good indicator of its service life. Testing by an independent, third-party lab revealed that after 180,000 miles in severe service, Signature Series Multi-Vehicle Synthetic ATF resisted oxidation longer than required for new fluid to meet the Chrysler ATF+4 specification (see graph). Internal components, including the valve body and clutch plates (pictured), were virtually free of damaging sludge, deposits and wear, confirming the lubricant’s high level of protection for severe-service applications.<\/p>\n

\"\"<\/p>\n

The transmission’s valve body is clean and virtually sludge-free following 180,000 severe-service miles.<\/p>\n

\n

Protects Against Thermal Breakdown<\/strong>
Signature Series Synthetic ATF is formulated with high concentrations of antioxidants, making it naturally heat resistant. It provides outstanding protection against sludge and varnish deposits that clog narrow oil passages and contribute to clutch glazing. After 180,000 miles in severe service, fluid analysis revealed Signature Series Multi-Vehicle Synthetic ATF contained 83% of its original oxidation inhibitors, proving its long-lasting resistance to thermal breakdown.<\/p>\n

\"\"<\/p>\n

\n

Outstanding Wear Protection<\/strong>
Varying speeds and loads causes torque multiplication and extreme stress on gears and bearings. AMSOIL formulated Signature Series Synthetic ATF with high film strength and premium anti-wear\/extreme-pressure additives to help prevent wear during severe service. In the industry-standard FZG Gear Wear Test, Signature Series Multi-Vehicle Synthetic ATF that had been used for 180,000 severe-service miles achieved a “Pass” at stage 12 \u2013 the highest stage. The results exceeded the Ford MERCON V and Chrysler ATF+4 specifications for new fluid, demonstrating the lubricant’s long-lasting wear protection.<\/p>\n

\"\"<\/p>\n

After 180,000 severe-service miles. The clutch plates demonstrated only trace discoloration and earned a rating of “good,” the highest possible, for deterioration\/wear.<\/div>\n
\n

Cold-Temperature Fluidity<\/strong>
Cold, thick automatic transmission fluid lengthens shift times and reduces fuel economy. Signature Series Synthetic ATF is wax-free and delivers extraordinary cold-flow properties. It helps improve shift response, energy efficiency and warm-up times.<\/p>\n

\n
Friction Durability<\/strong>
Today’s transmissions are smaller and must withstand higher horsepower and torque while delivering smoother shifts, all with longer fluid life recommendations. AMSOIL Signature Series Synthetic ATF is formulated with friction modifier additives that deliver outstanding clutch-holding capacity (static friction), torque-transfer ability (dynamic friction) and anti-shudder properties (slipping torque-converter clutches). Analysis reveals that after 180,000 miles in severe service, Signature Series Multi-Vehicle Synthetic ATF provides nearly identical friction properties as new fluid for smooth, reliable shifts.<\/div>\n

APPLICATIONS<\/u><\/strong><\/p>\n

\n
Use AMSOIL Signature Series Ultra-Low Viscosity ATF<\/strong> in transmissions and other applications that require any of the following specifications:<\/div>\n
\n
    \n
  • Ford MERCON ULV<\/span><\/li>\n
  • GM DEXRON ULV<\/span><\/li>\n<\/ul>\n<\/div>\n
    <\/div>\n<\/div>\n
    \n

    SERVICE LIFE<\/u><\/strong><\/p>\n

    Normal Service:<\/strong> Follow the vehicle manufacturer’s normal-service drain interval.
    Severe Service:<\/strong> Double the vehicle manufacturer’s severe-service drain interval in passenger cars and light trucks.
    Change at the vehicle manufacturer’s recommended drain interval outside U.S. and Canada.<\/em><\/span><\/p>\n
