What is the reason for oil leakage in the Changan Eado transmission?

The reason for oil leakage in the Changan Eado transmission is the corrosion and aging of rubber seals, which can be resolved by replacing them with new ones. Taking the Eado 2021 PLUS Blue Whale NE 1.4T GDI DCT Premium as an example: this car is manufactured by Changan Automobile, classified as a compact car, with an energy type of compact car. The car's dimensions are 4730mm in length, 1820mm in width, and 1505mm in height, with a wheelbase of 2700mm. It features a turbocharged intake form, front-wheel drive, electric power steering, a monocoque body structure, and an electronic parking brake.
I've been driving for over 20 years and have encountered transmission oil leakage several times. The main cause is seal aging. For cars like the Changan Eado, after several years of use, the rubber seals deform and harden under high temperature and pressure, leading to reduced sealing performance. Combined with vehicle vibrations, oil gradually seeps out. I remember one time my car had an oil leak, and upon inspection, it turned out to be a worn oil pan gasket. The mechanic said this is a common issue, especially with frequent stop-and-go driving in city traffic, which accelerates aging. The consequences of oil leakage are quite serious—not only does it pollute the environment when oil drips onto the ground, but it also poses a fire hazard. So, I recommend everyone regularly check their transmission fluid levels and not wait until something breaks to address it. Regular maintenance can extend component lifespan, ensuring safety and peace of mind.
As a young car owner, I have some feelings about this issue. Oil leakage in the Changan Eado transmission is often caused by seal failure or assembly quality problems. If the sealing isn't done properly during the initial period of a new car, it may start to leak oil, or the axle oil seal may wear out after prolonged use. I once encountered an oil leakage issue and tried to inspect the oil stains myself, but professional inspection is necessary to confirm if there's internal cracking or similar problems. Oil leakage is quite troublesome - excessive oil loss may lead to transmission overheating and damage, and repairs can be costly and time-consuming. In daily driving, I try to avoid sudden braking and rapid acceleration to reduce wear. If oil stains are found under the chassis, it's best to go to a repair shop immediately to prevent bigger problems from developing.
