Does a Manual Transmission Need Transmission Fluid Replacement?

[StLuke]

Manual transmissions do require transmission fluid replacement. The replacement interval for manual transmission fluid is relatively long, typically every 2-4 years or 60,000 kilometers. If the vehicle is not used intensively, it can generally be replaced every 100,000 kilometers. However, for high-intensity usage, it is recommended to replace the fluid every 60,000 to 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. The hazards of not replacing transmission fluid are as follows: 1. Weak Acceleration: Prolonged failure to replace transmission fluid may result in weak acceleration when starting the vehicle cold. 2. Cooling Failure: Over time, transmission fluid thickens, which can obstruct the transmission cooler, leading to excessively high fluid temperatures and increased wear.
