No grease fittings according to the lubrication chart but other things can also be causing sticking or locking issues. Packard had quite a time with locking problems with prewar linkage even though revisions were made. Clipper based bodies still had some issues thru the 22 and 23 series.
You might have a look thru the many service articles of things to check. Once the page opens look at the gearshift, linkage, and lockup articles. Several have also found serious wear at the stubs at end of the shift rods where they insert into the bushings at various levers to be a significant issue.
There is one additional place you might try lubing. I believe a common lube issue Clipper and conventional linkage experience is the two levers at the bottom of the column and shift tube near the steering box. While they are differently shaped, I believe the prewar conventional body arragement was same in that the upper 2-3 lever had no provisions for any kind of lube. Water condensing on the shift tube could run down and that and dirt could get in the space between the lever and tube. Rust and corrosion in that space can cause the lever to stick or actually seize to the tube.
The two levers -- bottom 1-R and upper 2-3 must be absolutely free to independently rotate on the tube. If the upper 2-3 lever is sticking and turns while shifting into 1 or R, the geometry of that linkage can move the 2-3 transmission lever first and cause the interlock block in the transmission to lock out 1 or R.
Here is a photo showing the Clipper tube and levers. You might compare the basics to yours and see if there are similar places you can lubricate.
