This is what is says when I login to My Ford...

Upon further investigation.... This is the heavy use maintenence schedule.

 

bosco - The owners manual for the 5.4 does not mention any transfluid change?

Go back a few posts and see the official Ford post on the 5.4 trans. The change of 30K miles is for the 4.6 trans as per my book.

 

their is no way any company would have a tranny fluid that doesn't need to be changed that would be money out of their pockets i agree with 30000

 

I guess you better go back to Ford and debate it with them!

Look under the heavy use maintenance schedule. That is where I found this. Under normal use it does not say to change it till 150,000 miles...

 

I agree it is listed under heavy useage,but if you read the preface to the special operating conditions section, it says if you occassionaly drive in these conditions it is not necessary to follow the special operating schedule.

With that said I am not a proponent of not changing the trans fluid. I am only responding on what Ford has said.

 

I personally would classify using a plow hard all winter long as "heavy use"...

 

I just paid $159 at my dealer for a full tranny flush on my 5.4.

 

5.4 is for life.

 

The Scheduled Maintenance Book states to do your change at 30,000 just like bsocko stated, I have yet to see anything about Lifetime ? I have never had any vehicle that I left the tranny fluid in for more than 20,000 miles and never had any issues so just do it between 20 and 30 thousand and you will be fine, Transmissions are like women, If you dont do the maintenance sooner than later all you will have is problems. it aslo says to do it every 30, 000 miles, 30,60,90 etc.. Now if you have a 6r60 trans that changes everything, but we are not talking about that tranny we are talking about a 4R75W...Like talked about before Using a plow would fall under special operating conditions, normally that it how they get you to spend more money and doing the maintenance, you may not need it but it doesnt hurt either, Excessive ! I Think Not !

 

It's been said in this thread MANY times. If your driving falls under the "severe conditions" category then change the fluid every 30k. BUT if you just drive the thing and tow every other week the service manual states 150k. I personally change it every 60k or whenever it looks like it needs to be changed.

 

The 30K is for heavy useage not normal driving conditions. As stated in the schedule maintenance book, occassional heavy useage does not warrant using the heavy useage schedule!
I also change at 60K, not a flush but a filter and fluid change.
