Synthetic Automatic Transmission Fluid Synthetic Automatic Transmission Fluid Synthetic Powershift Transmission Fluids Synthetic Supershift Racing Transmission Fluid Automatic Transmission Efficiency and Life AMSOIL ATF Exceeds Latest General Motors DEXRON®-III Requirements Use where ATF is recommended in Mobile or Stationary Hydraulic and Power Steering units. As automatic transmissions have become increasingly complex, the performance requirements of transmission fluids have increased. Reduced fluid sump volumes, continuously slipping torque converter clutches, six-speed transmissions and increased power densities significantly increase the level of stress put on a lubricant. In response, General Motors recently introduced a higher quality factory fill ATF, and in order to ensure their transmissions continue to receive adequate protection, they have upgraded their DEXRON®-III specification for service fill transmission fluids.“If we look at the kinds of fluids that are being blended out in the marketplace some of them are a long way away in terms of performance from our current factory fill, because they are still based on blends that had been formulated a number of years earlier,” said GM Transmission Fluid Group Leader Roy Fewkes. “The objective of the DEXRON® specification is to make sure that GM customers, wherever they are in the world, have a fluid that is appropriate for their transmission. So there was a need for us to upgrade the specification in order to make sure that the service fill fluids in the market are more representative of the factory fill performance that the transmission has been designed for.” To ensure protection for transmissions with reduced sump volumes and higher operating temperatures, the new DEXRON®-III specification requires a longer Oxidation Test. Fluids are now required to maintain performance for 450 hours, up from 300. GM expects the new oxidation requirements will be the most difficult for lubricant manufacturers to meet. In addition, DEXRON®-III calls for quicker de-aeration times to accommodate smaller sump volumes. Because today’s transmissions must handle increased torque and transmit more power, thermal stability is crucial for DEXRON®-III fluids. The combination of higher operating temperatures and reduced oil volumes calls for fluids that can not only maintain performance at higher temperatures, but also for longer periods of time. Electronically controlled converter clutches, implemented to improve transmission efficiency and fuel economy, are sensitive to the frictional properties of lubricants. Because friction modifiers are adversely affected by increased temperatures and fluid oxidation, GM introduced a new EC3 Low Speed Friction Test to ensure friction performance is maintained for as long as possible. The increased quality standards of the new DEXRON®-III specification could signal the end of Group I base stock use in ATF formulations. “The basic additive performance will essentially remain the same and people will have to adjust formulation in order to get them past things like the Oxidation Test,” says Fewkes. “But essentially what it {the new DEXRON®-III specification} is doing is driving the formulations away from Group I towards Group II base stocks.” AMSOIL Synthetic Automatic Transmission Fluid (ATF) exceeds the requirements of the new DEXRON®- III transmission fluid specification. It resists thermal and oxidative degradation up to three times longer than conventional fluids and twice as long as the new 450-hour DEXRON®-III test requirement. It protects clutches, planetary gears, valves, pumps and seals from damaging sludge and varnish deposits and ensures cool, smooth transmission operation for intervals up to three times longer than recommended by the vehicle manufacturer.

PRODUCT DESCRIPTION AMSOIL Synthetic Automatic Transmission Fluid exceeds the performance requirements for domestic and foreign automatic transmission fluid applications. AMSOIL ATF provides automatic transmissions, power steering units and hydraulic equipment with excellent lubricating protection and better performance over a wider temperature range than do conventional petroleum fluids. Resists Oxidation and Thermal Degradation AMSOIL ATF resists thermal and oxidative degradation up to three to five times longer than conventional transmission fluids do. It protects clutches, planetary gears, valves, pumps and seals from damaging sludge and varnish deposits. AMSOIL ATF helps prevent component overheating and ensures cooler, smoother transmission operation. Provides Low Temperature Protection AMSOIL ATF outperforms petroleum fluids in low temperature fluidity. In fact, AMSOIL ATF offers three times the cold temperature fluidity required by current automatic transmission fluid specifications. AMSOIL ATF provides easier starting, faster warm-ups, smoother shifting and improved fuel economy. Anti-Wear Protection AMSOIL ATF provides smooth shifting and long, trouble-free transmission life. In addition, the anti-wear additive package makes AMSOIL ATF an excellent lubricant in other hydraulic systems. In tests designed to measure wear characteristics under severe service and high pressure operating conditions, AMSOIL ATF far exceeds the requirements of hydraulic equipment manufacturers. Extended Drain Intervals AMSOIL ATF is formulated for extended drain intervals. Transmissions usually operate under severe service conditions. They are subjected to extensive idling, frequent short trips, cold temperature driving, sustained hot weather driving or trailer towing. When conventional transmission fluid is used, it should be changed every 15,000 to 30,000 miles. AMSOIL ATF should be changed at intervals up to three times longer than the recommendations of the vehicle manufacturer. APPLICATIONS AMSOIL Synthetics Automatic Transmission Fluid is completely compatible with other synthetic and petroleum automatic transmission fluids. AMSOIL ATF is a universal, multifunctional fluid and greatly reduces the need for specialized fluid inventories and the possibilities of misapplication. SERVICE LIFE AMSOIL ATF has an expected fluid life of three times the automatic transmission manufacturer's recommendations. Drain intervals may be extended indefinitely when fluid analysis is used. |

AMSOIL ATF Maximizes Automatic Transmission Efficiency and Life |
Over 40 percent of total energy loss in an automatic transmission can be attributed to the act of pumping
automatic transmission fluid to the transmission's working components during transfer of power. The mechanical efficiency of an
automatic transmission is directly affected by the viscosity of the transmission fluid. When
temperatures drop and cause ATF to thicken, transmission efficiency and power decline.
Industry tests on torque loss demonstrate that a temperature increase of 150 degrees F increases transmission efficiency by up to 37.5 percent. In other
words, as viscosity decreases, transmission efficiency increases.
Higher quality automatic transmission fluids can have a profound impact on transmission efficiency. Automatic transmission fluids with lower cold temperature pumpability properties effectively keep transmissions running efficiently during cold weather, maximizing both trans- mission power and fuel economy. The Brookfield Viscosity Test gauges a transmission fluid's viscosity in cold temperature conditions. Current industry specifications dictate that Brookfield Viscosity not exceed 20,000 cP. While the average conventional transmission fluid has a Brookfield Viscosity of 15,000 cP, AMSOIL Synthetic Automatic Transmission Fluid far exceeds the minimum standard with a Brookfield Viscosity of 7,454 cP, ensuring maximum transmission efficiency and power even in the coldest winter temperatures. AMSOIL Synthetic Automatic Transmission Fluid exhibits out- standing oxidation stability, pre- venting viscosity increase that leads to reduced transmission efficiency and cold temperature performance. While the use of AMSOIL ATF ensures maximum transmission efficiency, its shear stability and premium anti-wear additives also ensure superior wear protection, exceeding industry standards in the Four-Ball Wear Test, FZG Test, Vickers Wear Test and Falex Extreme Pressure Test (see test results below).
