Annoying gear shift

Hi!

I have my eye super major. The gear shift is weird. When in 1/3 and wanting to select 2/4 it is blocked. Only way to select it is to shift to reverse or 6/5.
And then the 1/3 is blocked. So in other word I cant shift from 1/3 to 2/4 and vice versa directly.
What is happening?
 
All the shift lever and shift fork components in the Major transmissions are secured to the shift rails by tapered end set screws, into
tapered sockets, and secured by tie wires, I have seen them break the wires and back out part way, making them sloppy to shift, or back out
completely and not able to shift, Extreme wear on the shift slots, shift lever, and or ball socket could also cause that condition. Usually
happens on loader tractors, due to frequent sloppy shifting habits.
 
You can check the shift ball and socket and set screw by putting it in neutral and removing the shift tower. Also check fit of shift lever
in the tower. I don't remember if you can access the shift fork anchors from there. A 77 year old, cobweb filled brain, that hasn't seen the
inside of one for over 50 years.
 
Maybe you know but the dipstick by the gearshift is for the rear end and the transmission fill plug is by the clutch cross shaft. Both take same oil. 15W40, 30 or 40 weight work fine.
