What Causes Transmission Oil Leakage?
2 Answers
Transmission oil leakage occurs due to the deterioration of the sealing performance of the transmission oil pan gasket. In such cases, simply replacing the transmission oil pan gasket is sufficient. When replacing the transmission oil pan gasket, it is essential to go to a professional institution and have it done by professionals using specialized tools. The transmission is a crucial component in a vehicle, connected to the engine and part of the drivetrain. The transmission can change speed and torque, allowing the engine's power output to meet the vehicle's needs under any operating conditions. There are three common types of automatic transmissions in vehicles: AT transmission, CVT transmission, and dual-clutch transmission.
I've been driving for over twenty years and have encountered transmission oil leaks several times, mainly caused by aging or damaged seals. Rubber seals can harden and crack over time, allowing oil to seep out; loose or corroded oil pan bolts are also common – during my last long-distance trip, I noticed oil stains under the car and found the bolts weren't tightened properly; transmission case cracks can also occur, such as from hitting a pothole or prolonged corrosion. Significant oil leakage leads to insufficient transmission fluid, causing severe gear wear, overheating, or even seizure. Regularly check for oil drips under your parked car, and if you notice strange odors or gear shifting issues, get it repaired promptly. I recommend inspecting seal components during regular oil changes to prevent problems. Repairs can be costly but are essential – delaying them can lead to major trouble.
