What might a clogged transmission filter cause?

A clogged transmission filter can indeed lead to transmission overheating. The primary function of the transmission filter is to trap debris and contaminants from the transmission fluid, ensuring that the fluid remains clean and can circulate freely. When the filter becomes clogged, it restricts the flow of transmission fluid, which is essential for lubricating the internal components and maintaining optimal operating temperatures. If fluid cannot flow properly, it can cause the transmission to run hotter than usual, potentially leading to overheating and severe damage over time.

In contrast, erratic shifting can occur due to various factors including issues with the valve body or control solenoids rather than just a clogged filter. Fluid leaks are typically associated with damaged seals or gaskets instead of filter conditions. Additionally, it is inaccurate to assert that a clogged filter would have no impact on performance, as the restriction of fluid flow directly affects the transmission's ability to function smoothly and efficiently.
