Red Line (50304) MT-90 75W-90 Manual Transmission Lubricant – 1 Qt, 4-Pack

Red Line MT-90 is a high-performance synthetic gear oil designed for manual transmissions and transfer cases. It provides smooth shifting and excellent protection for gears and synchronizers.

Key Features:

  • Designed for many Nissan, Mazda, Mitsubishi, VW/Audi, Toyota, and Lotus manual transmissions, as well as Mendeola transmissions and Atlas off-road transfer cases
  • Helps provide smoother and quicker shifting
  • Helps reduce hard or notchy shifting, especially when the transmission is cold
  • Safe for brass synchronizers because it does not contain the reactive sulfur additives found in many GL-5 gear oils
  • Provides excellent protection against gear and synchronizer wear
  • Helps extend synchronizer life
  • Suitable for applications calling for 75W-90, 80W-90, or 90-weight gear oil
  • Also meets the viscosity range of SAE 40, 10W-40, and 15W-40 motor oils
  • Recommended for GL-1, GL-3, and GL-4 applications, including many manual transmissions that require special synchromesh fluids
  • Works well in both high-mileage and newer transmissions
  • Can be mixed with petroleum-based and other synthetic lubricants

Why MT-90?

Many GL-5 gear oils are designed for differentials and can be too slippery for manual transmissions. MT-90 is designed to provide the right amount of friction for proper synchronizer operation while still offering strong gear protection.

Important: MT-90 is not recommended for differentials with hypoid gears.
