1. Worn or Damaged Seals
Seals are designed to prevent transmission fluid from escaping. Over time, these seals can become worn, cracked, or brittle, allowing fluid to leak out. This is a common problem, especially on older vehicles.
2. Loose or Damaged Transmission Pan
The transmission pan holds the transmission fluid. If the pan is loose or damaged, it can cause leaks. This can happen due to age, impact damage, or improper installation.
3. Cracked or Damaged Transmission Case
The transmission case houses the internal components of the transmission. If the case is cracked or damaged, it can leak fluid. This is usually caused by impact damage, improper repair, or corrosion.
4. Overfilled Transmission
Overfilling the transmission can cause fluid to leak out of the vent. Always check the transmission fluid level with the engine running and the vehicle on a level surface.
5. Worn or Damaged Transmission Lines
The transmission lines carry fluid to and from the transmission. If the lines are worn or damaged, they can leak fluid. This can be caused by age, corrosion, or physical damage.
6. Improper Transmission Fluid
Using the wrong type of transmission fluid can cause the seals to deteriorate and leak. Always refer to your vehicle’s owner’s manual to ensure you are using the correct fluid.
7. High Transmission Temperatures
High transmission temperatures can cause the seals to break down and leak. If you notice your transmission overheating, have it inspected by a mechanic.
