Ford 5610 Transmission query

[Alan L]

Hi There. New here.
Trying to sort a friends 5610. Got it running but something in the trans is baffling. Downloaded an e manual, but seems to be for wrong Gen. There were at least Gen 2 and maybe 3(?). So the answer is not in there.
To do with gear selection. Have got it running by not using selector rail for 3-4.
The interlock detents seem wrong. On the 1-2 rail there is a detent groove at each end of the rail (nothing in the middle). This means the interlock plug can only free up the 3-4 rail when 1-2 is engaged in a gear. The 3-4 rail has one groove - in the center of the rail (neutral). So it is locked when the 1-2 rail is in neutral and can only free itself when the 1-2 rail has a gear selected. This means 2 gears selected when using the 3-4 rail.
Has anyone figured this problem out? Something seems wrong here.
Thanks in advance
Alan from NZ.

Something IS wrong here. What do you mean by "got it running"? Is this a pre existing condition this newly acquired tractor came with, or has the transmission been apart and worked on? The purpose of the interlock mechanism is so only one shift rail at a time can be shifted out of neutral. What you describe sounds like something is assembled incorrectly.

I wonder if a shifter fork setscrew has loosened allowing fork to relocate on a shifter rail?
