Synthetic ATF:
This product is an approved GM Dexron II, Ford Mercon, and Mercedes Benz Automatic Transmission Fluid and is suitable for GM, late model Ford, or any vehicle which uses Dexron IID or Dexron IIE or Mercon for refill. Superior stability allows high-temperature operation without varnishing valves and clutches. Also provides improved shifting in cold weather.

Racing ATF:
Designed for use in racing automatic transmissions which need the positive shift of a Type-F automatic transmission fluid, Racing ATF contains no slipperiness additives, producing faster shifts and quicker lock-up, and can reduce elapsed time in drag racing. A higher viscosity compared to conventional Type-F transmission fluids provides higher torque converter efficiency at higher temperatures and the enhanced extreme-pressure protection provides five-times better film strength when compared to petroleum ATFs, reducing gear and clutch wear considerably.

Synthetic D4: Dextron II & III Grade
Redline's most popular and versatile automatic transmission fluid, D4 is suitable for use where Dexron III, Dexron II, or Mercon fluids are recommended. D4 provides a GL-4 level of gear protection, making it a superior product for transmissions and transaxles like the Corvette's T-56. The balanced frictional characteristics provide 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. It's stability allows high-temperature operation without varnishing valves and clutches. Also provides improved shifting in cold weather.

C+ ATF: Equivalent to Chrysler 7176 & ATF+4 (9602)
Satisfies the performance requirements of Chrysler types 7176 and ATF+4 (Type 9602), while providing 30% greater operating viscosity, 1/3 the evaporation of petroleum ATFs, and improved oxidation and sludge protection. Red Line C+ ATF also provides the best low-temperature shiftability in automatic transmissions allowing proper shifting at extremely low temperatures and will flow down to temperatures as low as -60°C. The improved wear protection makes C+ ATF the perfect automatic transmission or transaxle fluid for Chrysler vehicles.
