Manual transmission fluid is essential for protecting gears, synchronizers, and bearings in vehicles with stick-shift drivetrains. The right fluid reduces friction, prevents wear, and ensures smooth, precise shifting in a wide range of operating temperatures. Choosing a high-quality synthetic formula helps extend the life of your transmission while improving overall performance.
AMSOIL offers a complete lineup of manual transmission fluids engineered for demanding applications. The AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube delivers exceptional protection for heavily loaded gears, while the AMSOIL 5W-30 Manual Synchromesh Transmission Fluid is specifically designed for vehicles requiring lower-viscosity fluids for optimal synchronizer performance. For heavy-duty and commercial equipment, the AMSOIL SAE 50 100% Synthetic Powershift Transmission Fluid and AMSOIL SAE 50 Long Life 100% Synthetic Transmission Oil provide superior thermal stability and extended drain intervals.
Whether you drive a daily commuter, a performance vehicle, or operate heavy machinery, selecting the correct manual transmission fluid ensures reliable operation and long-term drivetrain health.
