If you disconnect the turnbuckle rods going to the transmission idler assy and have someone pull and hold the operator lever back toward the steering wheel like you were going to shift into first or reverse, the upper lever should be free to spin just like the lower lever does with the operator lever in the regular position.
The upper lever does not get any lube from the hole so unless someone remembers to oil it rust and corrosion can form between the lever and shaft. Both levers must be free to spin because only one lever at a time can move when you select a gear. If the upper lever is sticking and also turning when you select 1 or R it can prevent those gears from engaging.
The oil hole may be on the side of the shaft so somewhat hidden unless you look for it. A few drops in the hole will catch the finger on the splines that moves back and forth to select a lever when you pull the operator lever. A bit of oil will run out a slot and take care of the lower lever but unless you spill some getting in the hole oil will not reach the top lever.
Here is a shaft and lever showing the typical result of corrosion on the upper lever. Note how the shaft is rusty in the length the levers operate. The lower lever below the spines is corroded but has a bit of lube. Where the upper lever rotates is completely dry. The second photo shows the shaft after cleaning. The areas circled in red are what the oil hole will take care of. NOTHING reaches the top lever unless some spills out of the hole or you make an effort to place some oil at the top of the lever to let it run down the outside of the shaft and get in the space where the lever rotates..
