2008 F150 5.4 Transmission Flush

[Mid-Lake Rock]

The manual for my 2008 5.4 F150 says to flush the tranny at 60K. I'm at 34K and had my oil changed yesterday. The service writer told me I should get my tranny flushed and fuel filter changed. I told him the manual says 60K for the tranny and has nothing for the fuel filter. His explained that due to cold weather these items should be done around 30K.

Any opinions? I'm thinking I should just follow what Ford recommends. The power train is under warranty. As always, I appreciate any input. Thank you.

I recommend every 30k for fuel filters, and every 60k tranny flush and tune up.

It seems the dealerships have 1 set of numbers and Ford has another. When the dealership recommends things at mileage intervals we always go to the service manual but the explanation you always get are "these are just guidelines" to which I reply "they are guidelines by Ford and we will stick to those."

OK, let me add to my post, if you tow alot, or if the fluid is dirty, or smells funny, i will recommend it earlier.

Thanks guys. Yeah, I've read that if towing a lot it should be done earlier. I tow my boat short distances in the summer and move the wheel house around Mille Lacs, but that is about it. I think I'm going to keep an eye on it and shoot for somewhere around 50K.

One other question. What are your thoughts about when to drop the pan and replace the filter? Shop told me 150K is their recommendation. Thanks again.

I do them together. And it is a very smart thing to have done right before 60k. When the pan is down, if there are and metal chunks, or metal shavings in there, it would be best to catch that before 60, as Ford will still help you out with the bill. They may not pay it all, but will pay upto 80% if you are the original owner, and get your service work done at the dealer. Or at minimum, have the service records available to prove you have done all needed maintenance on schedule.

I do mine every 30k. Every time I have it flushed, I cannot believe the difference in how the truck shifts/drives. It is night & day.
