Red Line's High Temperature Automatic Transmission Fluid is a synthetic ATF which is a GL-4 gear oil for use where Dexron III or Mercon is recommended and is perfect for heavily-loaded vehicles. Its superior stability allows high-temperature operation without varnishing valves and clutches. Synthetic High-Temp ATF provides the gear protection of a GL-4 gear oil in an ATF and provides a higher viscosity at higher operating temperatures, allowing the transmission to operate at 70°F higher temperature and still provide the optimal shiftability and improved torque converter efficiency. The evaporation characteristics are significantly improved, being twice as good as our Synthetic ATF and five-times better than a petroleum ATF. The improved thermal stability significantly reduces the rapid evaporation of the ATF which can produce a frothing out the filler tube. The balanced frictional characteristics provides smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum ATFs allows high-temperature operation without varnishing valves and clutches which leads to transmission failure. This product can be used in manual transmissions which require ATFs and will provide much better gear protection than a petroleum ATF.


  • Red Line offers the widest selection of fully-synthetic ATF on the market today
  • Each offer improved thermal stability, maintain viscosity levels, and feature lower volatility while providing the required frictional characteristics of each fluid's OEM-style replacement
  • Reduced oxidation and lower volatility at high temperature
  • Allows high-temp operation without varnishing valves and clutches
  • Extended drain intervals
  • For heavily-loaded vehicles, allowing operation at up to 70°F higher while maintain thicker viscosity than traditional ATFs
  • Use where Dexron III®, Dexron II®, Mercon® or GL-4 gear oil are recommended
  • Dramatically less evaporation, less varnish of valves and clutches in extreme conditions
