Pure Estorlin Qualifier Trans Oil 75w80 Cs10x1Qt

Pure Estorlin Qualifier Trans Oil 75W80 CS from Klotz Synthetic Lubricants is a full synthetic transmission fluid designed for high-performance manual transmissions and differentials. It is engineered to provide extreme pressure protection and thermal stability, making it ideal for enthusiasts who modify their drivetrains with aggressive gear ratios and high-torque engines.

This transmission fluid maintains film strength under heavy loads that standard fluids cannot handle. The 75W80 viscosity grade ensures optimal shift quality across a range of temperatures while resisting viscosity shear in synchromesh units. Klotz incorporates proprietary anti-wear and anti-friction additives to create a robust boundary layer between gear teeth and synchronizer rings, which reduces gear clash and extends component life.

Ideal for turbocharged, supercharged, or naturally aspirated vehicles with manual transmissions, this fluid meets or exceeds the Caterpillar Series 10 performance standard. It ensures compatibility with modern synchromesh designs and provides superior demulsibility for moisture separation, which is critical for manual transmissions exposed to moisture intrusion.
