This is my first post on this site. I have learned a lot from others so I thought I would share. I tried to post this under maintenance but it wouldn't allow me to. I had my auto trans fluid replaced on my truck at 40k miles at the dealer, since I tow a lot with my truck. The Ford dealer told me Ford did not recommend replacing the filter ( ?? ). I found a Ford filter on Amazon for 80.00 and the tool was about 14.00.
Jack up the drivers side of the truck for more room to work.
This is the part number for the filter
this is the tool I bought. It takes the 1/2" size
The external filter is located between the oil and tranny pans
There are grey retaining clips on the passenger side lines. These pop off with your fingers or pry gently with a screwdriver. Do not remove the small bolt holding the filter in place. Leaving it secured gives you better support when pulling the lines.
The tool wraps around the steel line and push it in toward the filter to release the line. While it is pushed in pull straight out on the line. It takes a pretty good pull to pop it out. Be ready with a catch pan ( I wasn't!) to catch the fluid.
with both lines on the passenger side off proceed to the drivers side. These are 3/4 inch nuts. I used a flare nut wrench so I would engage 5 sides. A standard wrench would probably work fine.
Now remove the 10mm bolt which holds the filter in place.
Installation is just the reverse procedure. Remember to top off your ATF. I lost about 1/2 qt doing the filter change.
