Treat your manual transmission to the good stuff.

This is a 6-quart case of Red Line Fully Synthetic MT-85 75W85 GL-4 gear oil.

Red Line is legendary for making shifts smoother, especially in colder weather, and for protecting your gears under hard use.

This MT-85 is a popular choice for a ton of modern and older manual transmissions that call for a GL-4 lubricant.

With six full quarts, you'll have enough for most transmission jobs, with a little left over for topping up.

Give your gearbox the synthetic protection it deserves for longer life and better performance.
