Wholesome automated transmission fluid (ATF) sometimes seems vibrant crimson. This vibrant colour signifies contemporary fluid with optimum lubricating and cooling properties. Because the fluid ages and degrades, it may well darken, turning brown and even black. A burnt odor usually accompanies this colour change, signifying extreme degradation and potential transmission harm. Fluid that seems milky or cloudy could recommend contamination with coolant or water.
Sustaining the right fluid colour is important for correct transmission operate. Clear, vibrant crimson ATF ensures clean shifting, prevents overheating, and extends the transmission’s lifespan. Ignoring discoloration can result in expensive repairs or full transmission failure. Commonly checking the fluid’s colour and situation, as outlined within the car’s proprietor’s guide, represents a easy but essential preventative upkeep step.
