Red Line synthetic GL-4 manual transmission oil. One Quart.
- 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
