Don't see too many 4.9 F250's, it should have the zf5 in it. Does the clutch seem to work ok?

My guess is worn out clutch or bad slave cylinder. Unfortunately, I think you may have to pull the tranny to access the slave cylinder on the 5 speeds. Or so I have been told.

Do you have plenty of fluid in the clutch resevoir?

5speed issuse

there is plenty of fluid, the truck will drive fine just the shifting is bad, no noise in neutral, and yes come to the conclusion about pulling the tranny to r/r slave cylinder and while im in there the clutch and pressure plate..and maybe the fly wheel too

IIRC, the ZF has the slave cylinder outside the bell housing. The Mazda M5R2 has the slave cylinder inside the bell housing.

So, check your transmission type, you may not need to drop the entire transmission.

I thought the Mazda wasn't offered on the F250's.
