AMSOIL, 75W-90 Synthetic Manual Transmission & Transaxle Gear Lube, Universal Fit

AMSOIL 100% Synthetic Manual Transmission & Transaxle Gear Lube

Maintain peak drivetrain performance with AMSOIL 100% Synthetic 75W-90 Gear Lube. Specifically engineered for demanding applications where high heat, shock-loading, and increased torque place extreme stress on internal components, this lubricant is the ultimate choice for towing, heavy hauling, and high-performance driving. Unlike conventional oils that can thin out under pressure, AMSOIL creates a shear-stable lubricating film that stays exactly where it’s needed, reducing friction and ensuring your gears and synchronizers last significantly longer.

Designed to excel in severe-service conditions, this advanced formulation resists thermal degradation and oxidation even in the most punishing high-temperature environments. Whether you are shifting a high-torque New Venture NV-4500, a modern front-wheel-drive transaxle, or a high-horsepower street machine, AMSOIL provides the smooth, notch-free shifting and component longevity required to reduce maintenance costs. With specialized seal conditioners to prevent leaks and exceptional cold-flow properties for easy winter shifting, this gear lube is the "gold standard" for manual drivetrain protection.

Features

• Superior Wear Protection: Formulated with a thick, shear-stable film that shields internal gears and bearings from accelerated wear under high-torque loads.
• Extreme-Pressure Performance: Contains advanced additives designed to protect gear teeth against sudden shock-loading during heavy towing or aggressive driving.
• Smooth Cold-Weather Shifting: Excellent cold-flow properties ensure fast synchronizer engagement and effortless gear changes, even in freezing temperatures.
• Enhanced Thermal Stability: Resists oil breakdown and oxidation at high temperatures, preventing the formation of harmful sludge, deposits, and varnish.
• Advanced Leak Protection: Includes specialized seal conditioners to keep gaskets and seals pliable, reducing the risk of fluid loss and extending seal life.
• Severe-Duty Reliability: Specifically built for high-stress environments, making it a favorite for heavy-duty trucks and performance transaxles.
• Synchronizer Compatibility: Specifically balanced friction properties ensure consistent, crisp shifts without damaging yellow-metal synchronizer rings.
