* Complete transmission fluid and filter change: This requires the most ATF. The amount varies depending on the exact transmission your 2000 Plymouth Breeze 2.4L has. Your owner's manual will specify the capacity, or you can find this information online through a repair manual specific to your vehicle (Chilton's or Haynes are good sources). Expect to need several quarts (likely 7-10 quarts, but consult your manual for accuracy). You'll also need new ATF, a new filter, and a drain pan.
* Top-off: If your transmission fluid is low, you only need to add enough to reach the proper level on the dipstick. Check your owner's manual for the correct procedure for checking the fluid level, which is typically done with the engine running and at operating temperature. Only add a small amount at a time, rechecking the level after each addition.
* Transmission flush (not recommended): A power flush removes more fluid than a drain and fill, so it requires more ATF. However, power flushes are often discouraged because they can damage older transmissions.
In short: You need to consult your owner's manual or a repair manual to determine the correct amount of ATF needed for your specific task. Don't guess – using too much or too little ATF can damage your transmission.
