Automatic transmissions waste energy by creating excess heat from friction. AMSOIL synthetic ATF reduces friction to improve gas mileage and extend transmission life.

Synthetic Automatic Transmission Fluid Improves Gas Mileage and Diesel Fuel Economy
See prices or place an Order in the AMSOIL Online Store.
AMSOIL Synthetic Automatic Transmission Fluid (ATF) exceeds the performance requirements for all domestic and foreign automatic transmission fluid. It provides superior wear protection, smoother shifting, and improved gas mileage. AMSOIL ATF provides automatic transmissions with better performance over a wider temperature range than conventional transmission fluids and lasts up to 100,000 miles.

Saves You Money
This superior synthetic transmission fluid lasts 2 to 4 times longer that standard ATF fluid (up to 100,000 miles) and can save you over 50% on regular transmission service.

Resists Oxidation and Thermal Degradation
AMSOIL ATF resists thermal and oxidative degradation better than conventional transmission fluids, protecting 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 twice the cold temperature fluidity required by current automatic transmission fluid specifications.

Antiwear Protection
AMSOIL ATF provides smooth shifting and long, trouble-free transmission life. In addition, the
antiwear 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.

Extends Drain Intervals up to 100,000 Miles
AMSOIL ATF is a stable formulation that lasts longer in service than conventional ATFs. It maintains its viscosity, friction and lubricating properties for extended periods of time, even under severe conditions. AMSOIL ATF maximizes transmission performance and service life while reducing maintenance costs through longer drain intervals.

AMSOIL ATF resists thermal and oxidative degradation  better than conventional transmission fluids

AMSOIL Synthetic Universal Automatic Transmission Fluid is completely compatible with other synthetic and petroleum automatic transmission fluids. AMSOIL ATF is a universal, multifunctional fluid that greatly reduces the need for specialized fluid inventories and the possibilities of misapplication. AMSOIL ATF is recommended for transmission, hydraulic and other applications requiring any of the following specifications:

  • Chrysler ATF + through ATF +4
  • Honda Z1 (Not for use in CVT transmissions)
  • Toyota Type T and T-IV
  • Mitsubishi / Hyundai Diamond SP II & III
  • Allison C3, C4
  • Caterpillar TO2
  • Voith G607, G1363
  • ZF TE-ML 14A, 14B & 14C
  • Mercedes Benz 236.1, 236.2, 236.6, 236.7, 236.9
  • BMW 7045E
  • JWS 3309
  • NAG 1 & 2
  • Vickers I286S & M2950S
  • LT 71141 ESSO
  • Nissan Matic D, J, K
  • Excellent for power steering units that use ATF.      Not for use in CVT transmissions.

AMSOIL Synthetic Automatic Transmission Fluid is recommended for use up to 60,000 miles under severe service* and up to 100,000 miles under normal service* or according to the vehicle manufacturer recommended intervals, whichever is longer. AMSOIL recommends thoroughly draining the transmission and flushing with new AMSOIL ATF to achieve a minimum 90% purity of new transmission fluid. Drain intervals may be extended further with oil analysis.
