Common Sources of Transmission Fluid Leaks

Common Sources of Transmission Fluid Leaks

At the first sign of a transmission fluid leak, you'll want to promptly take the necessary steps to address it. If the leak goes unfixed, it could lead to major transmission trouble, perhaps even resulting in damage that requires you to replace your transmission. Here are five sources of leaking transmission fluid.

Faulty Transmission Line

Transmission lines run between different transmission components, and carry fluid from point to point. A bad connection in a transmission line could lead to a leak forming. Leaking could also occur due to a crack in a transmission line.

Worn-Out Transmission Pan Gasket

The transmission pan gasket creates the seal between the bell housing and the transmission pan. Over time, wear and tear can cause it to fail. When this gasket no longer provides a proper seal, a transmission fluid leak could occur.

Other Gaskets/Seals

In your transmission system, there are several seals and gaskets. When a seal's rubber wears down, parts could become misaligned, creating the opportunity for a transmission fluid leak to develop.


Your transmission consists of a number of moving parts that are subject to degradation. If parts such as the pan gasket or bell housing become cracked, then a leak could ensue. As soon as you become aware of a crack in any component of your transmission, you'll want to get the part repaired or replaced.


As you drive around, valves and solenoids play an important role in controlling the flow of transmission fluid. A transmission fluid leak could arise if you have a failing valve or solenoid.

If your vehicle has a transmission fluid leak that goes unaddressed, then your transmission could fail. If your transmission has failed and you need a replacement, be sure to order from a reputable supplier.
