Model G transmission issue

[Jake Buddy]

I've been using my G for the last 10 plus years with little trouble until recently. I started it one afternoon after using it all morning. I reversed it out of its parking spot then shifted from reverse to 2nd. It shifted out of reverse but did not shift into 2nd. It seemed to be stuck in neutral. I tried shifting to other gears and nothing. I did not hear any bangs though I had ear muffs on so who knows.

Anyway, I took out the shift lever and noticed a couple things. One was the grooves on the ball seem to be damaged/worn and the shaft seems slightly bent. The lever had always been a little loose but since it worked I figured why tinker with it.

Questions: is the shaft supposed to be bent? If I fix the grooves in the ball should this fix my issue or do I need to dig deeper? Do I need to reset the forks? If I take off the side cover what trouble will I get myself into? Finally, ever since I've owned the tractor it seems to slip out of gear every so often. I just put it back into gear and continue without a problem. Is this a symptom of the same problem or do I have another issue I should resolve while I have the tractor in the shop?

Thanks in advance for any advice!

I don't believe the shaft below the ball should be bent, but also not your problem. There are 2 pins that fit into those grooves and my guess is that they are what is worn. I think you can get replacements off this site.

Those worn grooves would go along with wear on the pins and the lower end should be straight. Slipping out of gear could be from the detents. Those are easy to fix. Just be careful when putting it back in. The pins tend to fall into the case if they are aligned with the slots.

The shifter should be straight. One of mine was bent like a banana. Put it in a press and straightened it out. The pins are to orientated a
certain way in the slots. If you have a manual go to page G-34 and it will show the pins. Where are the pins now? As far as removing the side cover goes have it in neutral and if you block up that side of the tractor the fluid will stay in.

I took the pins out when I took out the shaft. The manual state that the pins have a narrow side and are oriented depending on if the tractor has the special low gear. My pins don't seem to have a narrow side. Seems square to me. They are also a little worn so I plan to get replacements. Maybe the replacements will have a narrow side. I don't know if I have a special low gear. If I do I have never been able to shift into it. Is there a way to determine this without separating the transmission from the engine? I thought I saw a picture on another post where the low gear was outside the transmission.

I drained the fluid and plan to replace it. It hasn't been changed in years. I can't find a recommendation in the manual for viscosity just capacity. I assume based on other posts that it take 80/90 since it doesn't have hydraulics.

I replaced mine with universal hydraulic fluid. The creeper gear has been discussed a few times. I tend to believe maybe the early ones didn't have it but the rest do. It may not be engaged. And yes the gears are outside of the transmission. In the parts manual I only see the tapered pins listed. Both of mine have creeper gear but one wasn't engaged. It can be hard to shift into until you get used to it. Good luck!

“..I don't know if I have a special low gear…”
You do. All G’s had it. It was not special. It was just external from the regular 3-speed transmisson that was the same as on the B and C tractors.

From neutral you have to give the lever a twist to the right then down to get into extra low.
