How Much Transmission Fluid Does a Car Need?
1 Answers
A car's required amount of transmission fluid depends on the model and the replacement method. Generally, manual fluid replacement requires 4-6 liters, while using a fluid exchange machine requires about 9-12 liters. Transmission fluid is categorized into automatic transmission fluid (ATF) and manual transmission fluid (MTF). ATF should be replaced every two years or after driving approximately 60,000-80,000 kilometers, while MTF should be replaced every three years or after driving about 80,000-100,000 kilometers. Below are the hazards of not changing automatic transmission fluid for a long time: 1. Prolonged failure to replace transmission fluid can lead to abnormal wear and severe fluid degradation in the transmission. 2. Under high-speed and high-temperature conditions, old transmission fluid can deteriorate and evaporate, accelerating the wear of mechanical components and, in severe cases, damaging internal transmission parts, shortening the car's lifespan. 3. Long-unreplaced transmission fluid can become granular, clogging fluid passages and damaging valve bodies, directly affecting system oil pressure and power transmission, resulting in sluggish response and gear-shifting impacts.
