4 Common Sources of Transmission Fluid Leaks & Why They Should Be Fixed ASAP

Kenny’s Transmission • 12 March 2025

A transmission fluid leak can lead to serious damage if left unaddressed. Transmission fluid is essential for keeping internal components lubricated and preventing overheating. Identifying the source of a leak early can help you avoid costly repairs and keep your vehicle running smoothly. At Kenny’s Transmission, we provide expert transmission fluid leak repair in the greater Indianapolis area. Here are four common places where transmission fluid leaks occur.


Transmission Pan Gasket

The transmission pan gasket forms a seal between the transmission pan and the transmission housing, preventing fluid from leaking out. Over time, the gasket can deteriorate due to heat and wear, leading to small cracks or gaps. If the gasket becomes brittle or is improperly installed, transmission fluid may begin to seep out, forming puddles under the vehicle. Replacing the gasket can resolve this issue before it worsens.


Seals

Transmission seals prevent fluid from escaping at connection points throughout the system. These components can degrade over time due to exposure to heat and friction. Common areas where seal leaks occur include the input shaft and output shaft. When seals wear out, they may allow fluid to leak. Replacing worn seals can help prevent further fluid loss.


Torque Converter

The torque converter plays a crucial role in transmitting power from the engine to the transmission. It contains transmission fluid that helps transfer energy efficiently. If the torque converter develops a crack, fluid can begin leaking from this component. A leaking torque converter can lead to low fluid levels, resulting in transmission slipping or overheating. 


Transmission Pan

The transmission pan holds a significant amount of fluid and is secured by bolts. If the pan is damaged, corroded, or improperly tightened, it can develop leaks. Checking the pan for damage and ensuring bolts are properly torqued can help prevent leaks from forming. If the pan is in poor condition, replacing it may be the best solution.
