Transmission Fluid Evacuation Service:
Bulletin From Filter Manufacturers Council (16k PDF)
Transmissions in commercial vehicles, SUVs, trucks and vans – particularly
those used for hauling or towing – are subjected to severe-service
operation and increased heat. Elevated temperatures cause fluids to
break down, allowing damaging metal-to-metal contact and the formation
of sludge and deposits. The problem is worse in modern transmissions
with more gears, clutch packs and narrow oil passages that require
clean, high-quality fluid to achieve maximum performance and life.
AMSOIL Signature Series Synthetic Automatic Transmission Fluid is
specifically formulated to withstand the rigors of heavy towing, elevated
temperatures and challenging terrain. It remains fluid in sub-zero temperatures
and provides reserve protection during heavy use and even
abuse.
Proven in 180,000-mile, Severe-Service Taxi Fleet Field Trial
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.
Protects Against Thermal Breakdown
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 percent of its original oxidation inhibitors, proving
its long-lasting resistance to thermal breakdown.
Outstanding Wear Protection
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 – 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.
Cold-Temperature Fluidity
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.
Friction Durability
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.

automatic transmissions. (DEXRON VI specification
supersedes the obsolete DEXRON III in GM vehicles.)
SERVICE LIFE
Normal Service: Follow the vehicle manufacturer's
normal-service drain interval.
Severe Service: Double the vehicle manufacturer's
severe-service drain interval.
Change at the vehicle manufacturer's recommended drain interval
outside U.S. and Canada.
