Does the '04 f-150 4spd auto-trans have lifetime no-change fluid?

 

Yes it does.

 

Are you kidding me? How do they do this? Is it a new type of fluid? Transmission fluid breaks down with heat and use! I would be more interested in hearing about this!

even tho the trans fluid is considered to be life time fluid, my trans will still get serviced at 25k - 30k just like i normally would. fluid and filters are cheap, replacing major components are not. even tho under warranty now, what happens to the trans life several thousand miles down the road?

 

I have an 02 Explorer that has the sealed tranny with mervon v fluid...ford says not to service till 100,000....I had it flushed at 25,000 for the same reason as gmcplus03

 

I'll be servicing mine too at 25k interval. I also don't run oil additives or any other gimmicks that supposedly extend oil life.
