From the brand

Product Description

Red Line Synthetic Automatic Transmission Fluids are designed to provide excellent low-temperature shiftability and improved thermal stability over petroleum ATFs. These fluids provide a much lower viscosity at cold temperatures for quicker shifting and their balanced frictional characteristics provide smooth and consistent shifts over extended drain intervals. The superior stability compared to petroleum ATFs also allow high-temperature operation without varnishing valves and clutches, which leads to transmission failure.
