The total transmission fluid capacity depends on the specific transmission in the car: about 9–10 quarts for the 1.5L turbo with a CVT, and about 13–15 quarts for the 2.0L turbo with a 10-speed automatic.
In 2018, Honda offered two transmissions in the Accord: a continuously variable transmission paired with the 1.5-liter engine, and a 10-speed automatic paired with the 2.0-liter engine. This article explains the approximate capacities and the fluids used, noting that exact figures can vary by vehicle, service method (drain-and-fill vs. full flush), and market specifications.
Transmission options and capacities
Because the 2018 Accord came with two different transmissions, the fluid capacity figures differ accordingly. The following outlines the approximate total capacities when performing a full fill.
- 1.5L turbocharged engine with CVT: Total capacity ≈ 9–10 quarts (CVT fluid; Honda HCF-2).
- 2.0L turbocharged engine with a 10-speed automatic: Total capacity ≈ 13–15 quarts (ATF; Honda DW-1).
These figures serve as guidelines for service. The exact amount can vary based on model year, market, and whether you are performing a drain-and-fill versus a complete flush. Always consult the owner's manual or a Honda service bulletin for the precise specification for your vehicle.
Fluid types and checking levels
Fluids to use
CVT models require Honda CVT Fluid HCF-2. The 10-speed automatic uses Honda ATF DW-1. Using the incorrect fluid can affect shifting performance and long-term reliability, so verify the specification for your exact car.
Checking and refilling procedure
When servicing, ensure the engine is at operating temperature and the vehicle is on level ground. Follow the appropriate procedure for your transmission type—many newer Hondas use electronic level checks or a service bulletin procedure rather than a traditional dipstick. After adding fluid, cycle through the gears or drive the car as directed to circulate fluid, then recheck the level to ensure it is within the recommended range.
Summary
In summary, the 2018 Honda Accord’s transmission capacity depends on the drivetrain: the CVT version holds roughly 9–10 quarts, while the 10-speed automatic version holds roughly 13–15 quarts. Always consult the owner’s manual or a Honda dealer for the exact specification for your VIN, and use the correct fluid type—HCF-2 for CVT and DW-1 for the 10-speed automatic.
