Red Line offers lubricants to pinpoint nearly every transmission application. This has the most popularity, the most viscosity, and the most applications. Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection. It is compatible with petroleums and other synthetics and is excellent for high- and low-mile transmissions. MTL, MT-85, and MT-90 are not for use in differentials with hypoid gears. Red Line MT-90 High Performance Full Synthetic 75W20 GL-4 Gear Oil is a full-synthetic ester-based lubricant designed for use in manual transmissions and front-wheel-drive transaxles. This shear-stable formula resists breakdown for extended periods and offers more consistent viscosity in warm and cold temperatures for less gear noise and improved shifting. This fluid is less slippery for improved synchronizer coefficient of friction and offers stronger film strength for better wear protection. It is popular for BMW, Honda/Acura, Ford Focus, late-model Mini Cooper, Land Rover/Range Rover LT77S, Dodge & Jeep (NV1500, NV3500 , NV3550 and NV5600) truck transmissions. It is also a popular replacement for and improvement over GM Synchromesh (#12345349), Auto-Trak II (#12378508), and Chrysler spec MS-9224. This product is safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage. It also offers quicker shifts, has a perfect synchronizer coefficient of friction, eliminates notchy shifting (even when cold), and has high-performance gear protection and longer synchro life. In addition, it satisfies the gear oil viscosity requirements of 75W, 80W, and motor oil viscosities of SAE 30, 10W30, and 5W30. This product is recommended for GL-1, GL-3, and GL-4 applications as well as where most special synchromesh fluids are specified.

• Apt coefficient of friction for most manual transmission synchronizers
• Gear & synchro protection
• Balanced slipperiness
• Easier shifting in cold climates
• Great for high- & low-mile transmissions
• Works with petroleums & other synthetics
