Is Engine Transmission Oil Leak Serious?
2 Answers
Whether engine transmission oil leak is serious depends on different situations: 1. It's not serious when the leakage is slight; 2. It's serious when the leakage is severe. The causes of engine transmission oil leakage are: 1. Aging of oil rubber sealing ring; 2. Overload of transmission oil volume; 3. Vehicle chassis collision; 4. Aging and wear of engine crankshaft rear oil seal; 5. Excessive pressure in the crankcase. The solutions for engine transmission oil leakage are: 1. Replace the oil rubber sealing ring; 2. Drain part of the transmission oil; 3. Check the vehicle chassis; 4. Replace the engine crankshaft rear oil seal; 5. Inspect the crankcase.
My car also had a transmission oil leak issue last year, and that was definitely no small matter. At the time, I noticed the acceleration wasn't smooth while driving, and upon checking after parking, I found oil stains on the ground. If ignored, excessive oil leakage can lead to insufficient lubrication, accelerating internal wear of the transmission. In severe cases, it can fail to shift gears and break down midway—how dangerous that would be! Especially on highways, losing control could potentially cause an accident. I recommend getting it checked by a professional mechanic as soon as possible—don't try to fix it yourself. The cause of the leak might be something like a worn-out seal or loose bolts, and replacing these parts isn't too costly. Regularly cleaning the undercarriage and checking fluid levels during routine maintenance can prevent many issues. In short, safety comes first—don't wait until a major repair costs you a fortune to regret it.
