What is the characteristic color of new Automatic Transmission Fluid (ATF)?

New Automatic Transmission Fluid (ATF) is typically characterized by a pink hue. This distinctive coloration is a result of the additives and dyes incorporated into the fluid during manufacturing, which serve both functional and aesthetic purposes. The pink color helps in easily identifying the fluid among other automotive fluids, ensuring that it can be quickly recognized during maintenance checks or fluid replacement processes.

While other colors may also appear in ATF over time due to contaminants, thermal degradation, or oxidation, the fresh fluid's pink tint serves as a reliable indication of its condition. Therefore, when assessing the quality of ATF, the original pink color is an essential benchmark. This understanding is crucial for maintaining the performance and longevity of a vehicle’s transmission system.
