What Causes Red Transmission Fluid?
Transmission fluid is an intricate concoction of different chemicals, each serving a specific purpose. One of the factors that contribute to the red color of transmission fluid is the additives. These additives are deliberately mixed into the fluid during its manufacturing process to enhance its performance and protect the transmission system.
Some of the common additives found in transmission fluid include detergents, anti-wear agents, viscosity modifiers, and friction modifiers. Detergents work to remove and prevent the buildup of harmful deposits, while anti-wear agents reduce friction and protect against wear and tear. Viscosity modifiers help stabilize the fluid’s thickness under different temperatures, ensuring optimal performance.
Another factor that can cause transmission fluid to turn red is heat. As the transmission fluid circulates through the system, it encounters high levels of heat generated by the friction between the moving parts. This heat causes the fluid to oxidize, resulting in a red hue.
When the transmission fluid overheats, it can degrade much faster, leading to a loss in its lubricating properties. This can result in increased wear and tear on the transmission components, potentially causing long-term damage. Therefore, it is crucial to monitor the temperature of the transmission fluid and address any overheating issues promptly.
