What is a possible consequence of driving with faulty transmission fluid?

Driving with faulty transmission fluid can lead to serious issues for the vehicle's transmission system. Transmission fluid serves several crucial functions, including lubrication, cooling, and providing the hydraulic pressure necessary for the transmission to operate smoothly. When the fluid is dirty, contaminated, or has degraded, it loses its effectiveness in performing these roles.

As a result, the transmission may overheat due to the lack of adequate lubrication and cooling. This overheating can cause significant damage to various transmission components, such as seals, clutches, and gears, leading to potential transmission failure. The damage may require costly repairs or a complete transmission replacement, which could have been avoided with proper maintenance and fluid quality. Hence, the consequence of driving with faulty transmission fluid is the risk of overheating and subsequent damage to the transmission.
