Red Line ® High-Temp ATF is a fully-synthetic formula similar to D4 ATF, but with more viscosity for serious demands like towing and RVs. With eight different combinations of viscosity, slipperiness, and OE-recommended additives packages, Red Line offers the widest selection of ATF available. This High-Temp automatic transmission fluid is designed for heavily-loaded vehicles, allowing operation at up to 70 °F higher while maintaining thicker viscosity than traditional ATFs. Each Red Line ATF formulation offers improved thermal stability, maintains viscosity levels, and lowers volatility - providing the required frictional characteristics of each fluid's OEM-style replacement.

• 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
• Superior stability allows high-temperature operation without varnishing valves and clutches
• Red Line offers the widest selection of fully-synthetic ATF on the market today
• Reduced oxidation and lower volatility at high temps
• Better torque converter efficiency
• Perfect for heavily-loaded vehicles
