    Fully Synthetic. The Red Line MT-90 75w90 Fully Synthetic Manual Transmission Gear Oil is a great oil for your daily driven performance Mustang. Red Line's formula is formed from ester-based lubricant that resists breakdown for extended periods and offers consistent viscosity for less gear noise and improved shifting.

    Superior Protection. Being less slippery than other gear oils, the Red Line Synthetic Gl-4 Gear Oil features the appropriate coefficient of friction for most manual transmission synchronizers, offering proper synchro engagement and longer life. This MT-90 gear oil provides excellent wear and friction protection across a wide range of operating conditions and temperatures, even eliminating notchy shifty even when cold.

    Application. Red Line Synthetic MT-90 75w90 GL-4 Transmission Gear Oil is recommended for use in 1979 to 2014 manual transmission Mustangs, including LX, V6, GT, Bullitt, Mach 1, SVT Cobra, Boss and Shelby GT500 models. Sold individually in one quart bottles.

    Application Note. Five (5) quarts of gear oil are required for a regular transmission maintenance flush.

      Exceptional lubricant

      NO MORE CLUNKING

      This is great stuff. Transmission was making a clanking, clunking noise. This fluid cleared that up about 90.

      No more Notchy Shifting!

      I put this oil into my manual transmission in place of the old fluid, and it works great! I'd heard many good things from other owners, and decided to give it a shot, and definitely don't regret it. For a fairly high mile car, the trans shifts so much smoother now. Totally worth every penny.
