Automatic Transmission Fluids

Red Line Synthetic Automatic Transmission Fluids are designed to provide excellent low-temperature shiftability and improved thermal stability. The products identified as Synthetic ATF, Synthetic D4 ATF, and Synthetic C+ ATF have better thermal stability and lower volatility characteristics than a petroleum ATF and provides a much lower viscosity at lower temperatures, providing much quicker shifting in cold weather. 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.




D4 ATF Automatic Transmission Fluid
  • Our most versatile ATF, use where Dexron III®, Dexron II®, Mercon® and Mercon V® fluids are recommended, provides a GL-4 level of gear protection
  • Popular applications: Toyota Type T-III and T-IV, Honda ATF Z1, NissanMatic D, J, K, & S, Diamond SP-II, SP-III, Mazda ATF M-V, most BMW, Audi, VW automatic transmission
  • Also used with manual transmissions and transaxles like T-5, T-45, T-56 and late-model BMW
  • Excellent cold weather operation

D6 ATF Automatic Transmission Fluid
  • Our lowest viscosity, most shear-stable ATF for consistent operation
  • Designed to satisfy Dexron-VI®, Dexron-III®, Dexron-II®, Mercon®SP and Mercedes Benz NAG-2 fluids
  • Also satisfies API 70W/75W/80W and GL-4 gear oil requirements

Racing ATF Automatic Transmission Fluid
  • Similar to a Type F fluid, featuring even higher viscosity and no friction modifiers
  • Produces faster shifts, quicker lock-up, better converter efficiency at high temps
  • Enhanced extreme-pressure additives provide 5-times better film strength than petroleum ATFs
  • Reduced clutch and gear wear compared to petroleum ATFs
  • Satisfies GL-4 gear oil requirements

C+ ATF Automatic Transmission Fluid
  • Satisfies Chrysler ATF+, +2, +3 (Type 7176) and ATF+4 (Type 9602) requirements
  • Provides 30% greater operating viscosity and 1/3 the evaporation of Chrysler-style petroleum ATFs

Lightweight Racing ATF
  • Superior consistency and wear protection for Bracket and Heads-Up drag racing transmissions like Powerglide and Turbo 400
  • Popular with turbo and blown doorslammers like NMRA, NMCA, ORSCA, and PSCA -- replaces hydraulic oils and other non-ATFs used to escape heat issues
  • Low viscosity offers less frictional drag for quicker ETs and more MPH
  • Dissipates heat for longer trans life, better clutch, gear, and seal life
