Do Manual Transmission Cars Need Transmission Fluid Changes?

[BryceFitz]

Manual transmissions do require transmission fluid changes. Here is the relevant information: 1. The replacement interval for manual transmission fluid is relatively long, typically every 2-4 years or 60,000 kilometers. If the usage intensity is low, it can generally be changed every 100,000 kilometers, whereas for higher usage intensity, it may be changed every 60,000-80,000 kilometers. Transmission fluid operates under high temperatures for extended periods, which can lead to deterioration or evaporation, thereby accelerating the wear of mechanical components. In severe cases, it may even damage internal transmission parts. 2. The hazards of not changing transmission fluid are as follows: Prolonged failure to change the transmission fluid may result in weak acceleration when starting the car cold. Over time, the transmission fluid becomes thicker, which can obstruct the transmission cooler, leading to excessively high transmission fluid temperatures and increased wear.
