What is the effect of overheating transmission fluid?

When transmission fluid overheats, it can lead to a variety of serious issues, the most significant of which is the risk of transmission failure. Overheating can cause the fluid to break down, losing its ability to lubricate and provide hydraulic pressure within the transmission system. This breakdown of fluid results in increased friction and wear on internal components, leading to potential issues such as slipping gears, harsh shifting, and ultimately, a complete failure of the transmission.

Furthermore, the viscosity of the fluid decreases when it overheats, leading to inadequate lubrication of critical components. As a result, this can cause overheating of the transmission itself, which compounds the problem we could be facing. Thus, regular monitoring of transmission fluid temperature is essential to ensure the longevity and performance of the transmission system.
