What are some of the most common sources of transmission fluid leaks?

Keizer Transmission • 23 January 2025

Transmission fluid is essential for keeping your vehicle's transmission system lubricated, cool, and functioning properly. A leak can lead to serious damage if not addressed promptly. Understanding where these leaks typically originate can help you identify and resolve the issue before it becomes more expensive to address. 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.


Transmission Pan Gasket

The transmission pan gasket creates a seal between the transmission pan and the transmission housing. As the miles add up, the gasket can degrade, crack, or become loose, allowing fluid to escape. This issue is especially common in older vehicles or after improper installation during a fluid change.


Transmission Seals

Seals are used in the transmission system to prevent fluid from escaping at key connection points. Common areas for seal leaks include the input shaft seal, output shaft seal, and axle seals. Worn or damaged seals can allow transmission fluid to drip, often without immediate detection.


Torque Converter

The torque converter is a vital part of an automatic transmission system, transferring power from the engine to the transmission. A crack or faulty seal in the torque converter can lead to fluid leaks. These leaks are sometimes harder to detect because of their less noticeable location.


Transmission Pan

The transmission pan itself can become a source of leaks if it is damaged, rusted, or improperly installed. A bent or cracked pan may prevent a proper seal, leading to fluid leaks. Regular inspections can help identify and address this issue early.
