I have a 2002 Ford Focus wagon(US model). The maintaince manual says: "At 30,000 miles change automatic transmission/transaxle fluid on all vehicles equipped with AX4S,4F50N, 4R100, 4F27E. Inspect automatic transmission fluid level on all other vehicles."
That is interesting, we have the 4F27E auto transmission on our 2003, 1.6 Focus (UK), and there is no mention anywhere in the vehicle documentation regarding fluid changes. I've just spent 1 hour looking. It just states that the fluid level is checked during normal maintenance.
I am just about to change ours at 62,000 miles. The fluid is slightly darker than it should be.
You may have to ask a dealer which transmission you have. I suspect you may have the 4F27E too, as it is available on the 2.0 litre engine as well as the 1.6 litre.
