The CVT transmission fluid for the 10th-generation Civic is generally recommended to be changed every two years or approximately 60,000 kilometers. The transmission model is LL-CVT. The full English name of CVT is Continuous-Variable-Transmission, which means "mechanical continuously variable transmission," commonly referred to as a CVT. Different vehicle models have different replacement cycles. Below are the recommended replacement intervals for transmission fluid: Manual Transmission: Manual transmission fluid is generally recommended to be changed every three years or approximately 100,000 kilometers. Automatic Transmission: Automatic transmission fluid is generally recommended to be changed every two years or approximately 40,000 kilometers. Continuously Variable Transmission (CVT): CVT transmission fluid is generally recommended to be changed every two years or approximately 60,000 kilometers. Hazards of not changing the transmission fluid for an extended period: Damage to the transmission's shift control mechanism; Abnormal wear of gears and clutch plates inside the transmission; Impaired normal operation of the transmission, leading to damage to the transmission valve body.

As a 10th-gen Civic owner for three years, I've noticed CVT fluid changes are crucial. Honda's manual recommends replacement every 60,000km or 4 years, but for city driving with frequent start-stop like mine, it's better to shorten intervals to 40,000km to prevent fluid degradation. Transmission fluid not only lubricates internal components but also aids cooling - neglecting it causes jerky shifts, fuel consumption spikes, and even transmission control module failure. I regularly check the dipstick myself - fresh fluid is transparent red, while darkened/cloudy fluid signals danger. A professional service costs a few hundred yuan using OEM fluid for optimal compatibility. Long-term, frequent fluid changes prevent thousands in repair bills and extend vehicle lifespan.

I frequently deal with Civic transmission issues, where aging CVT fluid can impair smoothness. It's recommended to inspect every 50,000 km, or change every 30,000 km under harsh driving conditions. Deteriorating fluid quality affects lifespan, so timely maintenance saves money.

Just started driving a 10th-gen Civic as a beginner. The technician said the transmission fluid only needs to be changed every 60,000 kilometers. Don't stress too much, the manual is the authority. Changing the fluid is simple and ensures smooth driving.
