The causes of transmission oil leakage in the 10th-generation Accord: 1. Poor quality or materials of the engine and related components; 2. The engine operating at high temperatures for extended periods; 3. Loosening, tilting, or slipping of screws between the engine and components due to thermal expansion and contraction; 4. Damage to the engine caused by external impacts or collisions. The 10th-generation Accord is a mid-size sedan under GAC Honda, with exterior dimensions of 4893mm in length, 1862mm in width, and 1449mm in height, and a wheelbase of 2830mm. It is equipped with a 1.5T turbocharged engine, paired with a continuously variable transmission (CVT), delivering a maximum horsepower of 194 hp, a maximum power output of 143 kW at 5500 rpm, and a maximum torque of 260 Nm.
After driving for so many years, I've encountered transmission oil leaks, and the main cause is usually aging seals. The transmission sealing rings in the 10th-generation Accord can become brittle and crack under high temperatures and frequent use, leading to oil seepage. Another common issue is loose transmission oil fittings—under high pressure during aggressive driving, if the fittings aren't tightened properly or are worn, leaks can occur. It's also possible for the transmission casing to develop cracks, especially under prolonged rough road conditions, and factory defects can accelerate this. If you notice oil stains under the car or jerky shifting, check the oil level immediately and visit a certified repair shop as soon as possible. Never delay, as oil leaks can cause the transmission to overheat or fail, with repair costs running into thousands. For prevention, I recommend changing the transmission oil and checking the seals every 40,000 kilometers.
As an owner of the 10th-generation Accord, I've recently researched this issue. Transmission oil leaks are often caused by several factors: First, poor-quality or aged sealing rings that are prone to expansion and deformation under high summer temperatures, leading to leaks. Second, improperly installed connections, such as careless work during the last maintenance where the oil pipe fitting wasn't tightened properly, loosening after a few bumps. Third, excessively high transmission oil pressure, especially during high-speed rapid acceleration, where pressure surges may cause seepage. These issues can stem from design flaws or daily wear and tear. I recall some owners mentioning similar problems on forums. If you smell oil or notice oil stains on the ground, stop driving immediately and check if the dipstick fluid level has dropped. Safety first—if such leaks aren't addressed promptly, internal transmission damage can become a serious issue. It's advisable to visit a dealership for a detailed diagnosis, and avoiding excessive acceleration in daily driving can help reduce risks.
