Transmission oil leakage is serious and requires timely repair. The impacts of excessive transmission oil include: 1. Increased operational resistance inside the transmission, leading to abnormal oil leakage; 2. Agitation of the oil by rotating components can cause foaming; 3. Abnormal oil pressure may lead to air blockage in the drain holes of the control valve, resulting in poor drainage; 4. Gear shifting may become harsh. Precautions for changing transmission oil: 1. Choose the appropriate viscosity to avoid power loss; 2. Do not mix different types of oil to prevent adverse effects on the vehicle; 3. Avoid using low-quality transmission oil; 4. Ensure no impurities are introduced during the transmission oil change process.

Once I noticed oil stains under my car and found out it was transmission fluid leaking. At first, I didn’t pay much attention, but later the gears started shifting roughly with a grinding noise. After towing it to the repair shop, they found the oil pan gasket was cracked, and the low fluid level caused excessive wear on the clutch plates. The repair cost me 1,800 yuan, and the mechanic warned that if left unfixed, the transmission could be ruined, with a replacement costing over 10,000 yuan. Leaking oil leads to insufficient lubrication in the transmission, increasing friction between parts. The rising temperature can damage the metal structure. Regularly check the ground for oil drips when parked and inspect the dipstick’s color and fluid level. Addressing issues early saves hassle, money, and ensures safety. Remember, small problems can escalate—don’t delay.

The transmission fluid leak is indeed severe, as the fluid serves as the system's lifeline, lubricating gears and bearings while aiding in cooling and hydraulic control. After a leak occurs, the oil pressure drops, causing direct friction between components and accelerating wear. High temperatures may deform parts or cause oil to burn and deteriorate. Over time, the transmission may slip, shift slowly, or even seize up. The key is early identification: check if the fluid level drops or if there are red oil stains where the car is parked. The issue often relates to leak points such as the oil pan or aging seals. Repairing a minor leak may cost a few hundred, while ignoring it could lead to an exorbitant overhaul expense. Regular maintenance includes checking the fluid periodically—don’t wait for a breakdown.

From a cost perspective, oil leaks are troublesome. A minor repair like replacing seals might cost 300-500. However, if ignored and the oil runs out, transmission damage repairs start at several thousand, with a new transmission being even more expensive. It can also lead to towing or accident-related losses of time and money. In the used car market, vehicles with oil leak history suffer steep price drops. In short, early action prevents major financial loss—regular maintenance and oil checks are prudent budgeting. Oil leaks are often due to part aging; frequent inspections are crucial for older vehicles.

In terms of safety, transmission fluid leakage is extremely dangerous. Low fluid levels can cause the transmission to overheat and lose power, leading to sudden stalling or gear shift failure while driving at high speeds, which can result in accidents. This is especially terrifying in rainy conditions or on mountain roads where losing control of the vehicle can be disastrous. If you notice oil stains or abnormal operation, pull over immediately for inspection and visit a professional repair shop. Checking the fluid level during maintenance is crucial to prevent accidents. Never underestimate a single drop of oil—it can destroy safe driving.
