Castrol Transmax Manual 75W-90 1 liter can gear oil replaces Castrol Syntrans Transaxle replaces TAF-X Synthetic high-performance gear oil SAE 75W-90 1 can application Castrol Syntrans Transaxle (Transaxle Fluid) is a modern high-performance gear lubricant for manual transmissions and transaxle systems (manual transmissions and axle drive in one housing) of cars, vans and commercial vehicles. Thanks to its high thermal stability and the multi-range characteristic SAE 75W-90, Castrol TAF-X also covers the viscosity classes SAE 80, SAE 90 and SAE 80W-90, even in encapsulated gearboxes. Main advantages - minimized shifting forces under all climatic conditions - no hooking or cold scraping during gear changes - damping of transmission noise - fuel savings through improved transmission efficiency - reduced temperature level with extended service life
