Does the transmission fluid need to be replaced at 60,000 kilometers?
2 Answers
Generally, the manufacturer's recommendation for vehicle transmission fluid is to replace it every two years or 40,000 kilometers. However, this actually depends on the specific vehicle model, as different models have varying mileage and time requirements for transmission fluid replacement. Below are the detailed explanations regarding transmission fluid: Function: Transmission fluid is an oil product used to keep the gear system clean, providing lubrication to extend the lifespan of the transmission components. It offers effective lubrication even under low-temperature conditions and reduces fluid loss under harsh operating conditions. Depending on the transmission structure, transmission fluid is divided into automatic transmission fluid (ATF) and manual transmission fluid. Replacement: Under normal driving conditions, the temperature of automatic transmission fluid (ATF) rises to 80 degrees Celsius, which is the standard operating temperature for most ATFs. If the ATF can consistently maintain this 80-degree operating temperature, its lifespan can reach up to 150,000 kilometers. However, if the temperature rises higher, its service life will decrease accordingly. It is generally recommended to replace the transmission fluid every 80,000 kilometers.
As a seasoned driver with over a decade of experience, I consider changing the transmission fluid when my car reaches 60,000 kilometers. I've personally experienced that if not replaced in time, the transmission can become rougher, affecting gear shifting smoothness and increasing fuel consumption. Last year, my car developed strange noises due to neglecting this maintenance, costing nearly 5,000 yuan in repairs—far exceeding the cost of regular maintenance. Around 60,000 kilometers, the fluid is prone to oxidation and deterioration, losing its lubricating effectiveness. I make it a habit to regularly check the vehicle manual, as recommendations vary by brand. For instance, some Japanese cars suggest replacement every 40,000-60,000 kilometers, while European models might have longer intervals, but it's important not to skip it. Now, I take my car to the dealership every 50,000 kilometers for a check-up to ensure the fluid remains clear and prevent minor issues from escalating.
