A transmission fluid leak is a serious issue that can lead to significant damage to your car’s transmission. It’s important to address this issue promptly. Here are some common causes of transmission fluid leaks⁚
Worn-out Transmission Seals
Transmission seals are designed to prevent transmission fluid from leaking out. Over time, these seals can become worn out, cracked, or brittle, leading to leaks. This is particularly common in older vehicles.
Damaged Transmission Pan
The transmission pan holds the transmission fluid. If the pan is damaged, cracked, or has a loose bolt, it can cause a leak. This can occur due to a road impact or a previous repair that wasn’t done correctly.
Loose or Damaged Transmission Lines
Transmission lines carry the fluid between the transmission and the cooler. Loose or damaged lines can lead to leaks. Corrosion or wear and tear can cause this.
Faulty Transmission Cooler
The transmission cooler helps to regulate the temperature of the transmission fluid. A faulty cooler, such as a leak in the cooler itself or a damaged line connecting it to the transmission, can lead to leaks.
Overfilled Transmission
While it’s essential to maintain the correct transmission fluid level, overfilling can cause leaks. This is because excess fluid can put pressure on the seals, leading to leaks.
Other Potential Causes

- A faulty transmission pump
- A cracked transmission case
- A worn-out transmission filter

What to Do If You Suspect a Leak
