2004 f150 overdrive out

Apparently the transmission already has a problem if top gear does not work. You will probably see reduced fuel economy.

Yes it just yesterday started this problem of shifting to neutral instead of overdrive. But if I push the button to cut overdrive off it does fine in drive. I think after all that I have read I think the retaining ring on overdrive servo has broken. I will have to drive it until I can get it fixed $$$$&. Other than loss in fuel economy, could I hurt the trans if doing between 45 @ 50mph @ 2000rpm. My fluid is good color and does not smell burnt and at correct level when hot. How fast is too fast for the drive gear only?

I have the same truck, 2004 Ford F150 4.6ltr Triton V8, my overdrive is out as well. Seems like a common problem. Honestly if this is a common problem Ford should fix it free of charge!!! I was also told by a mechanic that the front servo has a problem of the clip breaking and falling down into the valve causing it not to shift into overdrive.

I have the same question so Can I DRIVES THE TRUCK JUST AS IT IT DIDN'T HAVE OVERDRIVE.

THE OVER DRIVE IS OUT ON MY 04 F150 AS WELL, RUNS FINE OFF AS I DRIVE TOWN ONLY BUT KILLING ME IN GAS. I WORK FOR AN AUTO REPAIR AND THIS IS VERY COMMON IN THIS TRUCK! FORD IS AWARE OF IT :(
