ABOUT RED LINE GEAR OIL FOR MANUAL TRANSMISSIONS
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
  • 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
  • MTL & MT-90 are not for use in differentials with hypoid gears
  • Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
