Red Line Synthetic Automatic Transmission Fluids are designed to provide excellent low-temperature shiftability and improved thermal stability. The products identified as Synthetic ATF, D6 ATF, D4 ATF, and 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.
Recommended where the latest Dexron-VI is required, as well as where Ford Mercon SP, Toyota WS and Mercedes Benz NAG-2 fluids are specified, Red Line D6 ATF satisfies the requirements for many of the latest automatic transmissions that require consistent, low-viscosity fluids that are shear-stable.
It provides the best low-temperature shiftability in automatic and manual transmissions which require ATFs. Also satisfies API 70W/75W GL-4 gear requirements
Most shear stable for consistent operation
Excellent low-temperature shiftability
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 recommends 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.
Our most popular and versatile ATF, D4 is suitable for use where Dexron III, Dexron II, or Mercon fluids are recommended. D4 ATF is a fully-synthetic product designed to satisfy the improved low-temperature requirements which will be in the new Dexron IV specification, and the improved shear-stability
