Red Line D4 Synthetic Automatic Transmission Fluid (1 Qt.)

The Red Line D4 Synthetic Automatic Transmission Fluid is designed to provide excellent low-temperature shiftability and improved thermal stability over petroleum ATFs. It provides 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 allows high-temperature operation without varnishing valves and clutches, which leads to transmission failure.

- 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 requirements which will be part of the new Mercon specifications.
