Installing the Filter:
Now before reinstalling the pan remove the old filter. It should come out really easily. However be careful that the seal of the filter has not come off into the filter bore (you can see the seal in the picture of the filter under the parts section above). When you remove the filter you should see this:
With the old filter removed wipe off any debris on the underside of the valve body, be sure to use a lint free cloth. Once finished install the new filter ensuring that it is properly seated, but not pressed into the valve body.
Now with the filter installed clean & inspect your pan gasket to see if there is any damage. If there is replace it. Mine looked suspicious in some spots so I replaced it to be on the safe side. Just for reference here is the comparison of the old gasket to the new one.
To install the pan and gasket you will need a 10mm socket and torque wrench. Set the torque wrench to 14 N-m(10.33 lbf-ft). Place the gasket onto the pan (only goes on one way because of the bolt pattern) and position it accordingly onto the transmission. Hand start bolts in each of the corners to hold the pan into position. Then proceed to install the remaining bolts by hand. Installing the bolts by hand ensures they do not cross thread. Once all of the bolts are in place torque each of the bolts down to spec. I started in the middle on all the sides and worked my way out to the corners.

Filling the Transmission:
Now having drained the transmission you need to determine how much was drained. I used an old measuring cup that have in my shop (mine drained a little over 2qts until it sputtered). Remove the dipstick and place the long ended funnel into the dipstick tube. Measure out the drained fluid a quart at a time adding in a new quart for each quart of old fluid drained. Once you have measured out all of the drained fluid repeat the draining procedure above. Continue to repeat this until you have evacuated the transmissions full capacity, which is 13.9qts (which includes the torque converter). I continued to drain the transmission until the fluid coming out looked as good as the fluid going in, which was at about 15qts.
(Note: New fluid is on the left)
Once you have flushed the transmission to your liking reinstall the line to the cooler. I could not find a torque spec for this, but I tightened it hand tight and then proceeded to tighten it with the 7/8" wrench until it was snug. Jack up the truck and remove all jack stands. Once lowered, start the truck, shift it through a few gears, and look around for leaks. Shut the truck off and clean up your work area ensuring no tools are in the engine bay or sitting on the chassis somewhere.
The mess I had to clean up:
Test Drive and Completion:
Once you have inspected your work and removed all tools and equipment you will need to take the truck for a test drive. Before you leave make sure to take the long ended funnel, a few quarts of Mercon V fluid, and some rags. To do this properly I would recommend driving the truck on a major interstate or highway at speeds of 55mph or more for 15-20miles. This is to ensure that the transmission fluid is up to operating temperatures. Once you have done this drive the truck onto a level ground. Shift the truck through all gears P-R-N-D-2-1 a few times leaving the truck in each gear for 15-30 seconds. Then engage your park brake and place the truck in neutral
. Remove the dipstick, wipe clean, reinstall and then take a measurement. I found that after the warm up test drive I needed to add half a quart to bring the dipstick measurement up to the 'hot' section.
With that, you should be done. Hopefully this helps everyone out and saves people some money. I know seeing pictures of the work is worth a lot and makes things much easier.
Just to give you an idea the dealership by me wanted $240 to change the transmission filter and perform a flush & fill. I had a total of $104.26 in OEM Ford parts and fluid. Total time for me to do the job was just under 2.5 hours, which included installing the drain plug kit. So if you are somewhat mechanically inclined you can save yourself some serious money.
