1940, 9N tractor Transmission problems

Hello everyone, I am new to this, but I have a 1940 9N tractor that has been sitting for about 3 years.
I got it running and it runs great. The problem that I have is that i cannot get it into any gear, either when its running nor when its shut off. No grinding or anything. (like its stuck in neutral)
Seems like the clutch is working fine, the pto works and when the clutch is pushed down the pto stops.
Also, it has a Sherman transmission that seems to be working.
i can engage and disengage it.
I took the fill cap off the transmission and sprayed some PBR blaster in there and hit a few things with a hammer and brass rod and still no luck.
My next option would be to take it to a qualify mechanic to have it worked on.
Any help here would be very much appreciated.

Thanks Steve K.
 
First thing I would do is loosen the 3 drain plug to the point you get drips of what ever is in there. If you get any water at all I would drain it and refill with 5 gal of fresh oil. Next run it for an hour or 2 and then try to shift it into gear. I've had more then one do that due to sitting and things rusting up but by running them the oil gets splashed around and in time frees thing up.

I think there is water in the transmission, when i check the dip stick, it looks a little milky.
I will try that this next weekend, the tractors at our camp.
I believe that it should take about 5 gallons of 90 wgt gear lube?

Thanks for the information.

I like Old's idea better than mine, at least as a first step. Step 2 would be to take the top off the transmission and see what's going on. Probably a shift fork has gotten out of its proper place.
 
I've had more then one where the shift rail has rusted up and in turn keep you from being able to shift it into gear. Had an 8N that would only go in a couple of gears but after using it for a while it would then sift as it should. Oil movement and heat freed things up
 

Can you move the shifter ?

Those shifters can easily be pulled up out of the gate/slot where it fits in the shift rail block I have done it several times by mistake.

Pull on it and check it, it will not hurt a thing...

I am sure you will get a small amount of water from the drain plug if its been sitting awhile its the nature of the beast as is milky oil...
 
Yes it takes just under 5gal. but putting in the full 5 will not hurt a thing. I'd pull the 3 drain plugs out and let it sit with them out for 24 hours if you can that way the water and oil milky oil will have time to drain out better. You might even try this. Add a bottle of HEET then fire it up and let it run for say 30 minutes so as to mix in the heet real good and also warm up the oil then shut it off and pull the drain plugs

Yes i can move the shifter side to side, and with the fill plug out it look looks like its still in the gate/slot.
I will try this if the heet/fresh oil and running for a couple hours doesn't work.

Thanks for all the information.
