Hard to shift when hot ?!?
Okay, so I've got an 1985 f-250 6.9 diesel.
First thing in the morning - shifts like a dream but . . . if I drive longer than 30 -40 minutes, I have to struggle to get it in to gear.
Any brilliant ideas?

Manual trans?
A few people have experienced this due to the firewall flexing more (& so the clutch master cylinder doesn't get it's full stroke) once the engine bay becomes hot.
Cold, it is stiff enough to not cause the problem.
A reinforcing plate has been the solution.

If its a manual trans Its time for a new clutch .The reason is as the clutch disc warms up it expands giving you less freeplay or clearance meaning your clutch is not fully releasing .I had this same problem with my 84

Seems to be a number of things that can cause the symptoms you describe. FWIW here's my thread about the same issue and how I fixed it.
