What kind of transmission fluid does a 2017 Toyota Corolla take?
For the 2017 Corolla, the required transmission fluid depends on the transmission type: if the car has a traditional automatic transmission, use Toyota ATF WS; if it uses a CVT, use Toyota CVTF WS.
Transmission options in the 2017 model year
The 2017 Corolla was offered with two different driveline configurations: a conventional automatic transmission on most trims and a Continuously Variable Transmission (CVT) on other trims. Each type requires its own specific fluid to ensure proper operation and longevity.
- Automatic transmission (traditional): Toyota ATF WS — the World Standard automatic transmission fluid recommended for most Toyota automatics since the mid-2000s.
- CVT transmission: Toyota CVTF WS — the CVT fluid designed specifically for Toyota’s continuously variable transmissions; do not use standard ATF in a CVT.
The fluid choice is dictated by the transmission type, not the model year alone. Using the wrong fluid can affect shifting performance and transmission life, so it’s important to verify which transmission your 2017 Corolla has before servicing.
How to confirm your transmission type
To be sure which fluid to use, consult the owner’s manual for your specific trim, check the vehicle information label under the hood, or contact a Toyota dealer with your Vehicle Identification Number (VIN). If your car’s CVT badge is present on the trunk or hatch area, it’s a strong indicator you should use CVTF WS.
Maintenance notes and tips
When servicing, always use the exact fluid specification listed by Toyota for your transmission. If you’re past the recommended drain-and-fill intervals, replace the fluid according to Toyota’s schedule, and consider having a trained technician perform a CVT-specific service if applicable. Never mix ATF WS with CVTF WS or other fluids.
Summary
In essence, the 2017 Toyota Corolla requires ATF WS for traditional automatic transmissions and CVTF WS for CVTs. Confirm your car’s transmission type via the manual or dealer if there’s any doubt, and always use the correct fluid to maintain proper shifting performance and transmission health.
