What are the benefits of changing transmission fluid for a car?
2 Answers
Changing transmission fluid benefits the car in the following ways: it makes gear shifting smoother, cleans and lubricates the gear system, extends the lifespan of the transmission components, ensures proper transmission operation, and can also reduce fuel consumption to some extent. New transmission fluid contains fewer metal impurities, reducing transmission wear and thereby extending the overall service life of the transmission while preventing minor issues. Here are the hazards of not changing automatic transmission fluid for a long time: 1. Prolonged failure to change transmission fluid can lead to abnormal wear and severe degradation of the fluid in the transmission. 2. If transmission fluid is not changed for a long time, it can degrade and evaporate under high-speed and high-temperature conditions, exacerbating wear on mechanical parts. In severe cases, it can damage internal transmission components, shortening the car's lifespan. 3. Not changing transmission fluid for an extended period can cause the fluid in the transmission to form particles, clogging the fluid passages and damaging the valve body. This directly affects the system's hydraulic pressure and power transmission, resulting in sluggish response and harsh shifting.
Changing transmission fluid offers numerous benefits. Firstly, it lubricates the gears and clutch inside the transmission, reducing friction and wear to extend overall lifespan. I once had a car that developed major transmission issues due to delayed fluid changes - the repairs were not only expensive but also caused significant inconvenience. Secondly, the fluid has cleaning properties that flush away metal particles and contaminants, preventing internal passage blockages. After fresh fluid replacement, the car drives noticeably smoother with jerk-free acceleration and quicker response. Regular fluid changes also improve fuel efficiency, saving money on gas. I recommend checking every 40,000-60,000 km and deciding based on vehicle condition - don't wait until problems arise. Developing this maintenance habit makes vehicles more durable and reliable.
