In the top of the transmission tower where the shift lever
rides, is a slot and a hole in the threaded part of the tower
where a 1/4" pin rides to keep the lever in alignment.
As it gets worn from many shifting`s, the slot widens out and the hole eventually wears and the shift lever gets sloppy and loose.
On my 67 International ton N half truck, I had the pin break
and the lever suddenly swing towards the dash as I was trying to get into 3rd. Took it apart and part of the threaded
part of the tower where the hole in, broke out.
Bought a new top cover and had to swap the shift forks etc...over.
