Transmission fluid plays a vital role in keeping your vehicle running smoothly by lubricating components, controlling temperature, and enabling proper gear shifts. When a leak develops, fluid levels can drop quickly, leading to performance issues and potential transmission failure. Understanding where leaks commonly originate can help drivers identify problems early and prevent costly repairs. At Keizer Transmission, we provide expert transmission fluid leak repair in the greater Salem, OR area. Here’s a look at four common sources of transmission fluid leaks.

Worn or Failing Transmission Pan Gasket

The transmission pan gasket creates a seal between the transmission pan and the transmission housing. Over time, heat cycles and age can cause the gasket to become brittle or crack. When this happens, fluid may slowly seep out, often leaving reddish to brownish stains on the ground beneath the vehicle after it has been parked.

Cracked or Damaged Transmission Pan

The transmission pan itself is vulnerable to damage from issues such as road debris or corrosion. Even a small crack can allow fluid to escape. Rust is another potential issue, especially in areas like the Pacific Northwest where vehicles are exposed to a lot of moisture. 

Damaged Transmission Lines

Transmission lines carry fluid through the system under pressure. Over time, these lines can become cracked or worn due to heat or contact with road debris. A damaged transmission line can cause fluid to leak rapidly. Because these leaks can worsen quickly, damaged lines should be inspected and repaired as soon as possible.

Leaking Input or Output Shaft Seals

The input and output shaft seals are under regular stress and can wear out over time. When these seals fail, transmission fluid may leak from the front or rear of the transmission.
