For those who drive manual, the transmission fluid should be changed every 30,000 to 60,000 miles. For those who drive automatic, however, this range increases to 60,000 to 100,000 miles. There's no harm in changing the fluid early, but there may be harm in waiting too long. What Is Transmission Fluid and Why Do We Have To Change It? Transmission fluid, in short, acts as a lubricant. It prevents various moving parts from grinding against each other and reduces friction, which reduces temperature, and thereby keeps the transmission cool. Over time, this important fluid naturally breaks down and becomes increasingly sullied by dirt and debris. The further it breaks down, the less effectively it will be able to serve as a lubricant; the less effectively it's able to serve as a lubricant, the more it will struggle to keep the transmission's temperature down. When not duly replaced, sub-optimally functioning transmission fluid will lead to wear and tear on th ... read more
