I was wondering how hard is it to change the internal filter on the transmission and fluids. Also if anyone can provide a step by step process to do so ( pictures would be nice), thanks.
I should add I'm mechanically inclined.

 

its really not that hard to drop the pan and change the filter but you will only change around 8 quarts of the 16 quarts or so the system holds if I'm not mistaken, you have to do a flush to change the oil in the converter ,which is better to be done by a shop that has a heated oil exchanger if you wont it done right.

 

I haven't done my 6.4 yet, but on my 5.4, I disconnect the cooler lines and let the engine pump it all out by idling. That makes dropping the pan out a lot less messy too (no drain plug)

Refill with fresh fluid, let the engine idle long enough until new fluid starts coming out. Turn it off, reconnect cooler lines, top-off remaining fluid, cleanup, and done. That's close enough to be a full flush.

Sir, this is the 2nd time I have heard about the heated oil exchange, and honestly knew nothing about it until a few weeks ago.
I am TOTALLY into doing all of the services on my own and even went so far as to buy a valve and gauge from Dieselsite to install along with my bypass filter when I am on leave in September.
After all of that, do you by chance have a link to a site I may obtain so as to better understand the "Tranny Fluid Heating" procedure?
I am wondering if I may be able to accomplish something like this on my own, as my wife recently paid the $224.00 to have FORD do it..
(And of course the question ALWAYS remains whether they did it correctly or not)
That was worse than the Fuel Filters they did when I first got the rig and before I learned how to do them myself.
Thank you for any incite I may get about this procedure.

I voted for the dealer to do the job. Torgue converter has a thermostat it it. Needs to be a heated flush in order to do the job properly.

Suggest that you look for your local quick lane to do the job instead of the actual dealership.

The quick lane is an authorized service facility thru ford

 

Thanks Senix-
Good Information

I am trying to decide if I'm gonna do mine myself or not as well. Some people are saying the flush is hard on the system seals and other components especially if the truck has high mileage and hasnt been changed in a long time. Even the dealer told me that sometimes they have problems after flushing high mileage trucks. I just bought a used 2008 F250 with 125,000 miles and want to do mine but I'm not sure if I should have it flushed or just drain and change the filters myself so any info on the subject would be great. I have a internal and external filter.
