Important considerations
- Check your owner's manual: This is the most reliable source for the exact capacity and fluid specifications for your vehicle.
- Initial fill vs. total fill: The initial fill capacity is for a standard fluid and filter change, while the total fill capacity accounts for a complete flush of the system.
- Use the correct fluid: It is crucial to use the manufacturer-recommended automatic transmission fluid (ATF) to avoid damage. Do not mix conventional and synthetic fluids.
- Checking the level: After filling, start the engine and run it through all the gears for a few seconds before checking the fluid level with the dipstick to get an accurate reading.
