The transmission fluid replacement interval for the Avancier 370 is every 2 years or 60,000 kilometers. The calculation method for transmission fluid replacement cycle is the same as the vehicle maintenance cycle - whichever comes first between mileage or time duration shall be followed. The automotive transmission is one of the crucial components of a vehicle, featuring excellent oxidation resistance that reduces component corrosion to some extent. Transmission fluid provides protective effects for gear sets while extending the transmission's service life. The Avancier is a mid-size SUV under Honda, with dimensions of 4858mm in length, 1942mm in width, 1670mm in height, and a wheelbase of 2820mm.

I've owned the Crown Road 370 for several years now, and as a family user, I'm particularly attentive to maintenance, especially when it comes to changing the transmission fluid strictly according to the manual. Honda's manual recommends replacing the transmission fluid every 40,000 to 60,000 kilometers or every two years, depending on your driving intensity. Since I frequently use this car for family outings and city driving, I make it a habit to change the fluid every 50,000 kilometers. Transmission fluid is like blood—it lubricates the gears and cools the system. Over time, the fluid can accumulate carbon deposits and thicken, affecting the smoothness of gear shifts, such as noticeable jerks when shifting from D to R. Prolonged neglect can damage seals or the hydraulic pump, leading to repair costs in the tens of thousands—what a waste! Every time I take the car to the dealership for maintenance, I check the fluid color. Fresh fluid is bright red, while darkening or a burnt smell signals aging. Although genuine fluid is more expensive, it offers the best compatibility, preventing future issues. Considering weather changes, I recommend checking the fluid early during summer's high temperatures and heavy loads to ensure worry-free driving. Don't underestimate regular fluid changes—they extend the transmission's lifespan, allowing it to run 100,000 kilometers without major repairs. This key step saves both hassle and money.

As a car enthusiast, I know the performance of the Avancier 370 like the back of my hand, and the transmission fluid replacement interval is something to carefully consider. Generally, it should be changed every 40,000 to 60,000 kilometers, but if you have high-performance demands, shorten it to 30,000 kilometers—like if you frequently drive up mountains or push hard on highways. I drive with a focus on explosive power, and transmission fluid lubricates and cools the gears. If it oxidizes and degrades, you'll experience delayed gear shifts and increased fuel consumption (I've tested and seen up to a 10% increase), completely ruining the driving thrill. I regularly check the dipstick; if the fluid changes from bright red to murky, it's time for a change. Otherwise, friction plate wear increases, leading to constant gearshift jolts. I recommend full synthetic oil—it handles high temperatures better and matches Honda's transmission design. It's a bit pricier but worth it in the long run. My routine: check the fluid quality myself every quarter and note the mileage during maintenance—don't delay too long. Ignoring replacements is risky—overheating can seize the transmission, leading to a costly repair (easily tens of thousands). Fresh fluid keeps the car running smoothly, with rock-solid performance. This small investment brings big driving pleasure!

Having worked in the repair industry for years, I've helped countless car owners with transmission issues. For the Honda Avancier 370, transmission fluid should typically be changed every 40,000 kilometers—strictly follow the manual, don't rely on guesswork. As the fluid ages, its viscosity changes, causing seal hardening and valve body sticking, initially manifesting as gearshift noise or shaking. I've seen cases where prolonged neglect led to metal debris buildup, resulting in major internal transmission damage requiring costly and time-consuming overhauls. Checking is simple: with the engine warm, pull the dipstick; if the fluid is dark brown with particles, it's time for a change. Always use OEM fluid to ensure quality, sticking to the 40,000 km interval to prevent minor issues from escalating. Based on experience, timely maintenance can extend transmission life by over five years at a fraction of repair costs. Choose a professional shop for the service to avoid incorrect refilling. In short, prevention is the core of maintenance.
