Product Description


Red Line's most popular and versatile ATF, D4 is suitable for use where Toyota T-IV, Dexron VI, Dexron III, Dexron II, Mercon, or Mercon LV 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 VI specification, and the improved shear-stability requirements which will be part of the new Mercon LV specifications.
  • Offers improved thermal stability, maintains viscosity levels, and features lower volatility while providing the required frictional characteristics of each fluid's OEM-style replacement.
  • Reduced oxidation and lower volatilty at high temperature
  • Allows high-temp operation without varnishing valves and clutches
  • Extended drain intervals

This fluid is a suitable replacement for the Mobil ATF 3309 used in the four- and five-speed transverse Aisin-Warner AW5x series, and for the Dexron III / Esso LT71141 used in longitudinal three- and four-speed AW and BW series transmissions.

Additional Technical Information

Early Volvo 3-speed automatics such as the BW35, BW55, and AW55 called for Type F transmission fluid instead of Dex/Merc. Type F fluid is "high friction" without any modern friction modifiers in it, so this fluid should not be used in transmissions calling for Type F unless the transmission has been serviced and the clutch and brake bands inside have been replaced with modern friction compound components.
