How to Determine When to Change Transmission Fluid?
2 Answers
Methods to determine when to change transmission fluid include: Increased gear shift hesitation, jerking movements while driving, or unusual noises from the transmission when the car is cold. Below are some related additional details: Transmission fluid replacement interval: The replacement interval is approximately every 40,000 to 80,000 kilometers. Functions of transmission fluid: It is a type of oil used to keep the gear system clean, ensuring the transmission operates normally, extending the lifespan of the transmission components, providing effective lubrication at low temperatures, and reducing oil loss under harsh operating conditions. Classification of transmission fluid: Based on the transmission structure, transmission fluid can be divided into: Automatic transmission fluid and manual transmission fluid.
My previous car had run nearly 150,000 kilometers, and I changed the transmission fluid twice. The lesson is to listen to the car's reactions. When you feel the gear shifts aren't smooth, especially when accelerating and it feels like something is dragging, or there's strange shaking even on flat roads, that's when you need to check the transmission fluid. Last time, I ignored these small signs, and the transmission almost got ruined. Also, older cars require more attention because aging seals are more prone to leaks, and low fluid levels affect lubrication. I usually check the fluid color every 30,000 to 40,000 kilometers—normally, it should be bright red and clear. If it turns brown or has a burnt smell, it's time to change it immediately. The maintenance manual's recommended intervals are just a reference; the key is to pay attention to the car's condition.
