I know several posters that do the 8 quart change every 10,000 and a few every 15,000. Just curious to know if running the 8 quart change's for 25,000 is over taxing the fluids ability to work.

Stock original injectors
Original headgaskets and headbolts

Alot of guys own one of these trucks cuz they wanted one and didnt need one.Dont tow and if they do its a jet ski or something a 1/2 ton gas truck could do.

If you wanna change your fluid every 10K knock yourself out.Iam just saying what has worked for me.

If your working your truck daily towing a backhoe or what not. pulling more than you really should then that maybe in your best interest to change at 10-15K.
If your towing a boat 3 times a year 20 miles.Go 50K iam sure youll be fine.

This is what happens when people rely on third party internet posts for their information.

Ford does not use the words "complete" or "flush" in the maintenance guide.

Here is the exact language from the 2005 Maintenance Guide.

Change automatic transmission fluid on vehicles
equipped with the Torqshift and 4R100
transmissions. Replace the remote filter element
on the vehicles equipped with the Torqshift
transmission.

And those Maintenance intervals are writen for people that use the truck for a purpose not for the pleasure of owning one.

In your diesel owners guide supplement it also says to "change engine coolant" at 105,000 Ford does not use the word "complete" or "flush" but only a jackass would think otherwise.

Even though most consider English more convoluted than other languages, the maintenance guide is written in short simple sentences for simple people however tall they may be.

My Ford Owner's Manual has no instructions for determining the height of a jackass.

Aw, why did you have to write that? Now he won't be able to sleep reliving all those incorrectly done oil changes.

Next time I add air to my tires, I will jack up the truck and vent all the old air out and refill with 100% new air. I've installed two bypass HEPA filters on my compressor after reading on the internet that air over nine months old accelerates rubber degradation by 32%. I don't understand why Ford didn't put that in the maintenance guide!

For those using Valvoline Max Life ATF:

How much are you paying for it? O'Reilly's charges more for it than either Motorcraft Mercon SP or Mercon LV.

A significant difference: you change a higher percentage of the oil in the system w/ a simple drain (14 or 15 quarts out of 18) vs what you do w/ the transmission (7-8 quarts out of 18). Again - quite a difference in percentage. Anyway, it is all about what works best and when it comes to transmissions, I would think a true test is at least 300k miles.

Glad you have had 190k miles w/ no issues, but I think it is premature to imply that there is little-to-no benefit to more frequent (or more volumetric) changes.

30000km drain pan, change ext filter. Rebuilt at 428,000km due to torque converter loose on flywheel. Re builder said there was still life left in it.
