Approximately 8 quarts for a standard drain-and-fill, with about 9 to 10 quarts if you perform a full system flush or replace fluid in the cooler lines and torque converter. The 2018 CR-V uses a CVT that runs on Honda DW-1 automatic transmission fluid, and the exact amount you need depends on the service method you choose.
Understanding the fluid and capacity basics
The 2018 Honda CR-V’s transmission is a continuously variable transmission (CVT) that uses Honda DW-1 ATF. Capacity figures can vary based on whether you’re doing a simple drain-and-fill or a complete flush, and whether you replace any internal filters or remove additional fluid from cooler lines. Always confirm with the owner’s manual or a Honda dealer for your VIN and regional specifications.
Estimated capacity by service type
The following figures reflect common service scenarios for a 2018 CR-V with CVT. They are approximate and can vary slightly by model year, trim, and regional specifications.
- Estimated total capacity (CVT system): about 8.0–9.5 quarts (7.6–9.0 liters)
- Drain-and-fill amount typically replaced: about 4.0–5.5 quarts
- Full system flush or complete replacement: about 9.0–10.0 quarts
Note: If your service includes replacing the transmission’s internal filter (if applicable) or flushing through the cooler lines, the total fluid moved may approach the higher end of this range. Always use Honda DW-1 ATF as specified by Honda for this model.
How to perform a change safely (general guidance)
If you’re considering a DIY transmission fluid change, follow these general steps to avoid overfilling or underfilling. Always refer to the official service manual for precise instructions and torque specs.
- Warm up the engine and transmission to operating temperature, then park on level ground and engage the parking brake.
- Gather the required tools, a drain pan, the correct amount of DW-1 ATF, and any replacement gaskets or seals if needed.
- Carefully remove the transmission drain plug (if present) and allow fluid to drain completely; replace the drain plug with a new gasket if recommended.
- Replenish the transmission with the specified amount of DW-1 ATF through the fill port or dipstick tube, keeping an eye on the level as you go.
- Cycle through the gears (P, R, N, D) with the engine running and the brake engaged, then recheck the fluid level when warm and the vehicle is on level ground.
- Inspect for leaks and dispose of used fluid responsibly. If you’re unsure, consult a qualified technician.
These steps are a general guide; CVT servicing specifics can vary, and incorrect fluid levels can affect performance and longevity. When in doubt, rely on a professional service center.
Bottom line
For a 2018 CR-V with a CVT, plan on roughly 8–9.5 quarts of DW-1 ATF for a typical service, with about 4–5.5 quarts replaced in a drain-and-fill scenario and around 9–10 quarts for a full flush. Always verify the exact capacity for your vehicle’s VIN with the owner’s manual or a Honda dealer, and follow proper procedures to ensure a correct fill level.
Summary
The 2018 Honda CR-V’s CVT holds approximately 8–9.5 quarts of DW-1 ATF. A routine drain-and-fill usually replaces about 4–5.5 quarts, while a complete flush can move about 9–10 quarts. Use the recommended Honda DW-1 fluid and consult the manual or a dealer for your specific vehicle to ensure accuracy and proper maintenance. Regular checks on level and condition help maintain CVT performance and longevity.
