TRANSMISSION FLUID CHANGE on 2002 Ford Explorer

WHAT IS THE CORRECT SCHEDULE FOR THE TRANSMISSION TO GET A CHANGE OF FLUID??? IS THEIR A FILTER TO BE REPLACE AND WHAT IS THE AVERAGE COST FOR THE JOB.

Asked by for the 2002 Ford Explorer
30,000 miles for severe duty; 100,000 miles for normal service. Lean towards severe. Have a fluid exchange service (flush) done to have the most productive fluid service.

ford saids change the fluid and filter on the 5 speed at 150k, realistically it should be done every 30 to 40 k
The owners manual will give you the intervals for trans service, make sure to follow the correct schedule for how you drive the vehicle. Yes there is a filter inside the trans pan. Check the estimator link on repairpal for estimate.
