Composition and Functionality The primary function of manual transaxle oil is to create a hydrodynamic film that separates moving gear teeth. The viscosity grade, often indicated by a code such as 75W-90 or 80W-90, determines how the fluid behaves across a wide temperature range, ensuring it remains effective in cold starts and stable during high-speed operation.

Therefore, it is vital to consult the vehicle’s specification guide to identify the exact API rating and viscosity required for the manual gearbox. For vehicles that are frequently subjected to stop-and-go traffic or heavy towing, more frequent changes may be necessary to prevent thermal breakdown of the lubricant.
Contaminated fluid may appear dark brown or black and feel gritty when rubbed between fingers, signaling the presence of metal shavings and debris that require immediate attention. The procedure involves draining the old fluid from the transmission pan, replacing the drain plug gasket, and refilling with the manufacturer-specified amount and type of oil.
