Redline MT-90 75W-90 GL-4 Manual Transmission and Transaxle Lubricant (4 Pack)

This high-performance gear protection product offers longer synchro life, ensuring quicker and smoother shifts. It provides the perfect synchronizer coefficient of friction, eliminating any notchy or uneven shifting, even in cold conditions. Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified, this product is safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that can cause damage.

Satisfying the gear oil viscosity requirements of 75W, 80W, SAE 40, 10W40, and 15W40 motor oil, this versatile lubricant is excellent for both high-mileage and low-mileage transmissions. It is compatible with both petroleum-based and synthetic oils, making it a reliable choice for a wide range of applications.

The advanced formulation of this gear protection product ensures superior performance and extended component life. The quick-shifting capability and the elimination of notchy shifting, even in cold weather, provide a seamless and precise driving experience. The lack of reactive sulfurs makes this product safe for brass synchros, a critical feature for maintaining the integrity of transmission components.

Versatility is a key strength of this gear protection solution. It meets the viscosity requirements for a variety of gear oil and motor oil specifications, allowing it to be used in a wide range of vehicles and applications. Whether you have a high-mileage or low-mileage transmission, this lubricant is designed to offer exceptional protection and performance, ensuring the longevity of your vehicle's powertrain.
