How does environmental degradation of transmission fluid affect the vehicle?

Environmental degradation of transmission fluid has a significant impact on the vehicle, specifically in terms of lubrication and overall performance. As transmission fluid ages and becomes contaminated due to heat, moisture, and particulate matter, its chemical composition changes. This degradation leads to reduced viscosity and the breakdown of essential additives that protect metal components within the transmission.

When lubrication is impaired, it can result in increased wear and tear on the transmission parts, leading to potential overheating and failure. The fluid's ability to transfer power and maintain smooth operation diminishes, which can lead to erratic shifting, slipping gears, and a higher likelihood of transmission failure. Therefore, properly maintaining transmission fluid not only supports the lubrication needs of the system but also ensures that the vehicle operates efficiently and reliably.
