D4 ATF Transmission/Transaxle Fluid by Red Line

Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection. This is our most versatile ATF, use where Dexron III®, Dexron II®, Mercon® and Mercon V® fluids are recommended, for use in automatic, manual transmissions and power steering.


  • Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
  • Red Line offers lubricants to pinpoint nearly every transmission application
  • Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
  • Excellent for high- and low-mile transmissions
  • Compatible with petroleums and other synthetics
