AMSOIL Synthetic Transmission Fluid

(Alternative AMSOIL Transmission Fluid Options Listed Below)

AMSOIL 20w50 Synthetic Motor Oil

AMSOIL synthetic automatic transmission fluid is a universal ATF designed to exceed nearly all foreign and domestic performance requirements. It improves fuel efficiency, reduces transmission temperatures by 20 to 50 degrees F and increases transmission life. Provides unsurpassed thermal stability and at least 3 times the life of conventional ATFs. Delivers maximum protection for towing and other severe-duty applications. Formulated with synthetic base stocks and the top-of-the-line additive package, AMSOIL ATF provides top performance, durability & efficiency.

Key Benefits to You:

  • Cleaner transmission components
  • More efficient power transfer
  • Lower Transmission temperatures
  • Dramatically less transmission wear
  • Smoother cold temperature operation
  • Long drain intervals

Compatible Applications

  • Applications requiring Honda Z-1 transmission fluids
  • Toyota TypeT, T-IV
  • Vickers I 286S and M2950S
  • ZF; TE-ML14B
  • Hyundai; SP-II, SP-III

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.

Recommendations for Use:

When switching to AMSOIL synthetic transmission fluid, drain the pan and then clean out any sludge and deposits. Clean metal shavings from the magnet. Replace transmission filter if there is one. Replace the pan (and gasket if necessary).

This procedure only removes the old fluid in the pan. There will still be old fluid in the torque converter - probably as much as was in the pan. To change this fluid to, it must be flushed out. You could either have a garage do it, or do it yourself. It's not that difficult. See our instruction page, for complete step-by-step directions for flushing the converter.

Once the full switch has been made, expect to extend change intervals to at least 3 times the vehicle manufacturer recommended change interval. If you do fluid analysis you'll likely find the fluid is good for far longer than that. Fluid analysis typically costs under $20.
