It will switch through all three of the other gears just fine but it will not shift into overdrive.  I have replaced both

Might be the linkage.

Does the truck have tow haul? Also could be the tcc switch. The only person who would think it was the linkage is the same person who needs help adding oil at the gas station. If it was the linkage then the truck wouldn't go into any of the other spots properly. N would be overdrive R would be neutral and P would be reverse and the truck wouldn't have park rolling down any slight grade it was parked on.

Also could be a bad overdrive band internal to the transmission.

How do you know it's not shifting into overdrive? Or, what is the vehicle doing to make you suspect this?

Your vehicle has a 4 speed transmission. After 3 shifts, you would be in 4th gear, which is overdrive.
