Transmission fluid leaks are a common issue that can occur in parked cars. While its normal to see a few drops of fluid under your car, especially after a long drive, a significant puddle of fluid is a cause for concern. Understanding the common causes of transmission fluid leaks can help you diagnose the problem and take necessary action to prevent further damage.
Common Causes of Transmission Fluid Leaks
- Worn-out Transmission Seals⁚ Seals are designed to prevent leaks by creating a tight seal around moving parts. Over time, seals can wear out, harden, or become brittle, leading to leaks.
- Damaged Transmission Pan Gasket⁚ The transmission pan gasket seals the transmission pan to the transmission case. A damaged or cracked gasket can cause transmission fluid to leak.
- Loose or Damaged Transmission Lines⁚ Transmission lines carry fluid between the transmission and other components. If the lines are loose, damaged, or cracked, fluid can leak out.
- Overfilled Transmission⁚ Adding too much transmission fluid can cause it to leak out of the transmission vent.
- Cracked or Damaged Transmission Case⁚ While less common, the transmission case itself can crack or become damaged, leading to fluid leaks.
