When the engine is running, the transmission system generates a lot of heat, which causes the fluid to expand and increase in pressure. This increased pressure can cause the transmission fluid to leak out through any weak spots in the system, such as worn seals or gaskets, loose connections, or cracks in the transmission housing.
Some possible leak locations are:
- Transmission pan gasket: The transmission pan gasket is located at the bottom of the transmission and is responsible for sealing the fluid inside. If the gasket is damaged or worn, it can leak fluid when the transmission is running.
- Transmission filter gasket: The transmission filter is located inside the transmission and is responsible for filtering out debris from the fluid. If the filter gasket is damaged or worn, it can leak fluid when the transmission is running.
- Transmission cooler lines: The transmission cooler lines are responsible for cooling the transmission fluid. If the lines are damaged or loose, they can leak fluid when the transmission is running.
- Transmission pump seal: The transmission pump seal is responsible for keeping the fluid from leaking out of the pump. If the seal is damaged or worn, it can leak fluid when the transmission is running.
- Transmission case: The transmission case is responsible for housing all of the transmission components. If the case is cracked or damaged, it can leak fluid when the transmission is running.
If you notice a transmission fluid leak, it is important to get it checked out by a qualified mechanic as soon as possible. Transmission fluid leaks can cause serious damage to the transmission and can even lead to transmission failure.
