D2 5J Diesel stuck in Reverse Gear

D2 5J S/N 1057 , after 1 year , I got this running / starting great . I used it for an hour on its test run and now It wont shift out of reverse. It had done it earlier after 15 minutes of useing, but only that time it was 2nd gear. I shut it off and restarted and it shifted out of 2nd gear that time. This time I removed the inspection plug and finally the shifter top for inspection. I found that one rod wont slide back to the neutral position. I readjusted the clutch . Nothing has helped. The clutch lever snaps overcenter great. The shifter its self works good so thats not the issue. thanks for any help

That sounds like the reverse/ second gear interlock needs some adjustment or repair.

I will check my manual as to this proceedure , thanks for the help !

There is a locking meck that works with the clutch and a rod goes from the clutch lever to the trans and locks it in whatever gear its in and sometimes the little pin loses it cotterpin and falls out if in lock position it will lock in gear and if in free position it will jump out of gear. .Open clutch cover and look inside

I will try this first thing in the morning, I will let you know the results , Thanks

I had that happen to my 5J as I was going through heavy mud and tried to back out.
What I found was a worn end on the shifter shaft. I was thinking interlocks also. But (in the woods again) I took cover and all back to civilization and the shop, welded up the end and ground it down to look as close to OEM as I could get it, back up in the woods, put it on and it worked, and has worked fine since.

I believe those early J models didn't have the shifter detent ball and spring interlocks so it was quite possible & common to engage two gears at once thus locking up the transmission. I'm sure well worn parts don't help the situation either. Later units had the interlock and I believe the earlier units could be converted.

About all you can do is pull the shift tower and fish around in there to manually move the shifter fork.

Here is the service bulletin:

I think we may all be missing the boat on this one.

If the problem is that the shifter won't shift out of reverse, but the stick is still in the correct shift gate (right side one I believe) and the tractor is still in reverse, and not two gears, then the end of the stick etc won't have anything to do with it. If the shifter gate is not still in the reverse position, the fork may have broken and left the gear engaged.

If the shifter gate is still in the reverse position and seems to be connected to the gear, it might be time to get a bar in there and carefully work the shifter forks back and forth a bit to save the stick from being damaged by all the heaving and shoving. First order of business would be to ensure that the other shift rails are returned exactly to the netural position in case the modification shown in OM's attachment is fitted.

The later system with the spring loaded detent/locking pins does not seem to positively prevent shifting two rails into engagement at one time, resulting in the problems we're all familiar with when the stick gets worn and slips out of the gate into the neutral area, allowing the operator to shift into two gears at once or at least preventing getting back into the correct gate.
