7 Best API GL-4 transmission fluids

7 Best API GL-4 transmission fluids

Categories
Fluids meeting API GL-4 standard for manual transmissions and transaxles. API GL-4 transmission fluids are designed to meet the American Petroleum Institute's GL-4 specification for manual transmissions and transaxles. These fluids provide moderate extreme pressure protection, making them suitable for synchronized manual transmissions in passenger cars and light trucks. They offer a balance of anti-wear properties and friction characteristics to protect gears and synchronizers while allowing smooth shifting. Users should verify if their vehicle requires GL-4 fluids, as using the wrong specification could lead to transmission issues or premature wear.
