It wasn't too hard.

I followed this thread for help.

I got my
drain plug drain plug
,
Wix filter Wix filter
and
anarobic gasket anarobic gasket
maker from Amazon for like $25. I got my fluid from Walmart, Supertech brand is like $4.50/qt, the cheapest I could find and works just fine.
Only thing I would do different is drill the pan first, I made a huge mess dropping a full pan.

I agree with having a pan with a drain plug. You should be able to find an OEM style pan with drain plug for a reasonable price. Look at the filter before you change it, most times a Ford trans filter is a wire screen. Not worth the effort to change in my opinion, it doesn't really do anything but block large debris.

This is my preferred method of trans maintenance, drain at oil change if fluid is even slightly discolored. Makes service so much simpler. If trans pan has a magnet remove it and use a magnetic drain plug.

I'de drop the pan, drain that fluid only, replace filter. Reassemble, top off fluid. Then after maybe another 1000 miles, do it all over again, drop pan, drain that fluid only, replace filter. Then maybe go another 3000k miles and do it all over again. Slowly cleaning it out and getting rid of any crap that might be in there instead of doing it all at once.

so I finally got the drop and fill yesterday. I let my local mechanic do it since he had the lift. He only charge me $40 bucks. The bad news is that the transmission was never serviced. It still had the OEM plastic plug that falls into the pan. There was a decent amount of big pieces of metal in the magnet. He suggested me to get it rebuilt as soon as I can afford it.

I do noticed the truck feels a little slugish taking off after the new filter and 5 quarts of fluid. Hopefully It lasts for a few months. I got a quote of $1200 from my local transmission guy.

You know the saying.

If it ain't broke, don't fix it. It could die tomorrow or it could die in another 100k. Don't rebuild on a account of what was on the magnet unless you have an issue.

But, $1200 is CHEAP as all get out. Mine was $3200 for a Ford reman.

I always put that plug with O-ring back in the Pan. Check the degas Bottle if you see any red or something that looks like rust the Oil Cooler is leaking ATF to the radiator and Coolant to the tranny when engine is off. Just install a Magnetic Filter and Replace the Oil Cooler including the Radiator.


It's Stupid to Flush any tranny components. It's impossible to clean Oil Cooler because there are too many small passages.

Instead of adding tranny drain plug just buy a Pneumatic/Manual fluid extractor. you can use it to suck fluid out of the dipstick tube. But you still need to remove the pan to insoect for metal particles sticking on the magnet.

$4 drain plug vs $50-100 for a Pneumatic Fluid Extractor. Granted you can use them for other purposes and many vehicles.

A manual hand pump only cost $10-15. You just need a large bottle and install a fitting that will fit the 2 hoses and seal it up. It's better than installing a drain plug that add another leak spot. It will be more easier to remove tranny fluid incase it was overfilled

Actually you only need the hose included in the pump because you easily create a Venturi by installing a small hose fitting in a garden hose near the faucet. When you turn the water on it will create suction.

I like where your head is at, but the $4 drain plug still has my vote.
