What is the transmission fluid capacity for a 1997 ford expedition v8 5.4?

The transmission fluid capacity for a 1997 Ford Expedition with the 5.4L V8 engine depends on whether it has a 4R70W or 4R100 transmission. Ford used both in that year.

* 4R70W: Capacity is approximately 11-12 quarts including the torque converter.

* 4R100: Capacity is approximately 16-18 quarts including the torque converter.

You absolutely MUST determine which transmission you have before adding fluid. Checking the transmission identification tag on the transmission itself is the most reliable method. Your owner's manual might also list the transmission type.

Do not simply add fluid based on an average. Overfilling can damage the transmission. The best approach is to perform a drain and fill, or better yet, a complete transmission fluid exchange at a professional shop. They will have the correct tools and procedures to accurately determine the fluid level.
