The automatic transmission fluid for the Honda Elysion should be replaced every 40,000 kilometers. The replacement interval and method for transmission fluid are as follows: Transmission fluid replacement interval: The general replacement interval is every two years or 40,000-60,000 kilometers. During normal operation, transmission fluid typically operates at around 120 degrees Celsius, thus requiring high-quality fluid that must be kept clean. Transmission fluid replacement method: The preferred method is dynamic fluid replacement using specialized transmission cleaning equipment. During operation, the old fluid is thoroughly circulated and completely drained before adding new transmission fluid, achieving a replacement rate of over 90% and ensuring optimal results.

When I first started driving the Elysion, I also struggled with the transmission fluid change interval. Later, I specifically consulted the master technician at the 4S shop. They recommended changing it every 40,000 kilometers or two years, whichever comes first. Actually, this car uses an automatic transmission. If you frequently drive in city traffic jams or on mountain roads, the transmission temperature tends to rise, accelerating fluid aging. I usually check the fluid color at 30,000 kilometers—if it turns black or has a burnt smell, I change it early. Once, I saw someone in the car owners' group wait until 60,000 kilometers to change it, resulting in severe transmission jerking and an 8,000-plus repair bill. So, it’s better not to slack off. When changing the fluid, remember to use the OEM-specified ATF fluid—a gravity change is sufficient, no need to remove the oil pan.

My Honda Elysion has been running for over five years, and I've been changing the transmission fluid strictly according to the maintenance manual – every 40,000 kilometers without any issues. Transmission fluid, just like engine oil, requires regular replacement. Over time, the additives in the fluid degrade, its cleaning capability diminishes, and metal particles tend to accumulate. Honda's manual clearly states that under normal driving conditions, the interval is 40,000 kilometers or 2 years. However, special conditions like frequent full-load uphill driving or operating in high-temperature weather can accelerate fluid deterioration. During the last service, the mechanic mentioned that the newer CVT transmissions have more complex structures, and delayed fluid changes might cause the steel belt to slip. Although a fluid change costs a few hundred yuan, it's far more economical than a major transmission overhaul.

My neighbor has worked in a repair shop for over a decade, and he mentioned handling many Odyssey vehicles that were scrapped due to not changing the transmission fluid. Simply put, it must be changed every 40,000 kilometers, which is basically an industry consensus. Transmission fluid primarily serves to lubricate and dissipate heat. Over time, metal particles mix into it, and the oil film strength diminishes. He taught me a simple way to check: if there's a noticeable jolt when shifting gears or if the RPM fluctuates erratically during acceleration, it's likely time for a change. Automatic transmission cars are most vulnerable to delayed fluid changes—once gear shifts become jerky, it's often too late. Some car owners try to save money by buying off-brand transmission fluid, only to find it oxidizes and degrades within three months, causing even more damage to the vehicle.
