Air - Every 30,000 - 40,000 depending on conditions
Fuel - Every 15,000 miles (or earlier if dirty/poor fuel is suspected)
Tranny - Every 30,000 or earlier if one tows a lot (only Mercon SP fluid)
By the way... the manual has most, if not all, of this in it....
Hope this helps... but it depends on how you drive and what performance mods you may have and how you treat your motor... but this is what I do with my stock 6.0L truck.

Where do you find the Mercon SP. I called the dealer and they said they use Mercon V. I could not find the SP anywhere.

Edit: I forgot to answer you question. Well honestly, I get it from my dealer. Did you contact your dealer's parts department? I bet the parts guy knows all about it. You probably talked to a Service Advisor who doesn't have a clue about these trucks.

The tranny's on the 6.0L motors are the first to use Mercon SP and any tranny's they have serviced with just Mercon V may have issues. So much for factory trained parts and service people!!!!!
They can and better order in as a regular stocked item for your next service!!!!

The torqueshift transmission was developed around Mercon SP or vice-versa... either way... the use of other fluids will not work well with this transmission. Mercon SP is also a synthetic fluid and has shown to be 100% reliable and no one since fall 2002 (here at FTE) has shown where it was the fluid that ever caused a transmission failure when regular fluid and filter intervals were adhered too.
On another note... one should not use Mercon SP in other transmissions that call for another type/formulation of fluid as well. It is "marketing"... certain trannies take certain fluids and no others... specialized marketing and production is what they call it... Ford calls it "increased profits"... but they are not the only auto manufacture to do so!!!
You may do the servicing yourself or have another facility do it... but just make sure the bottles of fluid they or you use say "Mercon SP" on them. I have also shown the secondary/external tranny filter that is located below the passanger side radiator area.
