Redline MTL

About Redline Gear Oil For Transmissions

  • 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-85 & MT-90 are not for use in differentials with hypoid gears
  • 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



  • Popular for BMW, Honda and Acura, Ford Focus, late-model Mini Cooper, Land Rover/Range Rover LT77S, Dodge & Jeep NV1500, NV3500 , NV3550 and NV5600 truck transmissions
  • Popular replacement for and improvement over GM Synchromesh (#12345349) and Auto-Trak II (#12378508) and Chrysler spec MS-9224
  • Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
  • Offers quicker shifts, perfect synchronizer coefficient of friction
  • Eliminates notchy shifting, even when cold
  • High performance gear protection and longer synchro life
  • Satisfies the gear oil viscosity requirements of 75W, 80W, and motor oil viscosities of SAE 30, 10W30, and 5W30
  • Recommended for GL-1, GL-3, and GL-4 applications as well as where most special synchromesh fluids are specified
