Castrol Transmax Manual Transaxle 75W-90 Transmission Oil

Castrol Transmax Manual Transaxle 75W-90 is a fully synthetic transmission fluid designed for manual gearboxes, transaxles, and transfer cases in passenger cars and light commercial vehicles. The advanced formulation ensures smooth gear shifting, reduced wear, and long-lasting transmission protection.

The 75W-90 multi-grade viscosity provides excellent performance across a wide temperature range: the 75W component ensures fluid flow and protection during cold starts, while the 90 grade maintains film strength and load-bearing capability at high operating temperatures. The fully synthetic base oil delivers superior thermal stability and oxidation resistance compared to conventional mineral oils, maintaining its protective properties over extended service intervals.

The fluid contains advanced additive technology that protects gear surfaces from micropitting, scuffing, and general wear, extending transmission life and maintaining shift quality. It meets or exceeds key industry specifications including API GL-4+ requirements. The Transmax Manual Transaxle 75W-90 is compatible with synchronised manual gearboxes and is specified by various vehicle manufacturers. Users should verify compatibility with their vehicle's owner manual before use. Manufactured by Castrol, a globally recognised lubricant brand within the BP group.
