How often should the automatic transmission fluid be changed for the Changan Eado XT?
3 Answers
Automotive automatic transmissions generally require the automatic transmission fluid to be changed every two years or every 40,000 kilometers driven. However, this can vary depending on the vehicle model, as different models have different requirements. For Japanese models, it is recommended to change the fluid every 40,000 to 80,000 kilometers. Vehicles that frequently drive at high speeds are advised to change the fluid approximately every 40,000 kilometers. Below is some relevant information about transmissions: 1. Introduction: A device that changes the speed ratio and direction of motion. It is used to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission typically consists of a housing and several pairs of gears. 2. Function: While driving, to adapt to different operating conditions, the vehicle's driving force and speed need to vary within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the need for a transmission.
I've been driving the Eado XT for four or five years, and I usually change the automatic transmission fluid every 60,000 kilometers or so. If I drive mostly in the city with frequent gear shifts due to traffic congestion, the fluid tends to degrade faster, so I change it earlier at 50,000 kilometers. I remember once delaying it until 70,000 kilometers, and I could clearly feel the gear shifts becoming jerky. The mechanic said the fluid had turned black. My advice is not to rely solely on mileage but also consider your actual driving conditions. If you frequently drive on highways or carry heavy loads, you can extend the interval slightly, but don’t exceed 80,000 kilometers. Also, for the first fluid change, it’s best to go back to the 4S dealership—they use original manufacturer fluid, which is a better match. After the change, the car drives noticeably smoother, as if the transmission has had a deep clean.
I bought my Eado XT two years ago, and it's an automatic transmission model. According to the maintenance manual, the automatic transmission fluid should be replaced every 60,000 kilometers or 4 years. However, I consulted a friend who works at a repair shop, and he mentioned that the quality of new cars has improved nowadays. If the driving conditions are good, such as not frequently stuck in traffic or engaging in aggressive driving, the replacement can be appropriately delayed. Personally, I plan to check the fluid color at 50,000 kilometers, and if it turns dark brown, I'll replace it earlier. Additionally, here's a detail to note: it's best to use a flush machine for a complete fluid change, even though it's more expensive, as it ensures all the old fluid is removed. Last time, a group member mentioned that a gravity drain wasn't thorough enough, and they had issues after just 10,000 kilometers, which ended up costing more in the long run.
