Common Causes of Transmission Fluid Leaks
- Worn-out Transmission Seals⁚ Seals are essential components that prevent fluids from leaking out of the transmission; Over time‚ these seals can wear out due to age‚ heat‚ and friction‚ leading to leaks;
- Damaged Transmission Pan Gasket⁚ The transmission pan gasket seals the pan to the transmission housing‚ preventing fluid leakage. If the gasket is damaged‚ cracked‚ or worn‚ it can cause fluid to leak.
- Cracked or Damaged Transmission Case⁚ The transmission case is the outer shell that houses all the transmission components. If the case is cracked or damaged‚ it can allow transmission fluid to leak out.
- Loose Transmission Lines⁚ Transmission lines carry fluid between the transmission and other components like the radiator or cooler. Loose or damaged lines can cause leaks.
- Overfilled Transmission⁚ Overfilling the transmission can put pressure on the seals and cause leaks. It’s crucial to maintain the correct fluid level.
Symptoms of a Transmission Fluid Leak
- Fluid Dripping or Puddling Under the Car⁚ The most noticeable symptom is a red or reddish-brown fluid dripping or pooling under the car‚ especially near the transmission area.
- Slipping or Rough Shifting⁚ Low transmission fluid levels can cause the transmission to slip or shift roughly.
