Oliver Transmission stuck

I have a 1968 Oliver that seems to be stuck in gear. When I let up on the clutch it wants to stall. The front shift lever seems to go into neutral but nope. Even if the transmission is stuck in gear it should move? It was working fine before the freezing weather came last week.

Thanks for any suggestions on what could be the matter.

It was working fine before it got below freezing. I took the cap off and there was no ice just old fluid.

The rails are stuck for sure but I'm not sure if that's it. I loosed one of the square nuts above the rail and it seemed to move some after that. Could be the brakes tho I'm wondering?
 
Water and 90wt. gear oil don't mix unless whipped together into a chocolate moose by the gears. When it sits even for a few days,
the water separates and goes to the bottom. When it freezes, the entire gear box becomes frozen into the ice. I wager there is 3
or 4 gallon of water in the bottom. Warm it up with space heaters of torpedo heaters blowing in from the hitch with a tarp over
the top. (be careful, and watch what you are doing) once thawed, drain out the water before moving it or starting it to avoid re-
mixing the moose. Jim
 
My JD430 transmission stuck last week. Not in 2 gears but would die if you let out clutch even if not in gear. We have had cold weather and hadn't used it since October. I used a magnetic heater and other heater on transmission case and now works fine. I assume a little moisture somewhere.
 
Read my post below. Drain the water out using the drain plug very loose so it can be re-screwed when only oil comes out. If the temps are still very cold don't use bare hands, you can get frost bite. Jim
 
You say you took the cap off. What cap?? It would help to know which model you have. They have drain plugs on the bottom of the transmission and rear end, 3 of them I believe. Water separates and goes to the bottom and freezes. If it was working fine until the weather got cold and now won't work, it didn't break anything just setting there. Get under it with a 1/2 inch breaker bar and take the plugs out, if nothing comes out, there's your problem. If you were using it and it happened, it's probably worn shift parts not shifting gears or else a gear is welded to the top shaft from lack of lube. Chris
 
Tim is that an Oliver 550? You could tarp it and put a ready heater
under it and drain the oil. If your shift boot is bad it funnels a lot of
water into the transmission. Cheap fix if you have water in the oil.
 



Even if your shift boot is good and the tractor has never spent a night outside there can still be gallons of water in there just from condensation.
 
I'm not THE expert on things, but, I have learned over the years that you're better off to heat the case up with a lamp for a few hours and bite the bullet and go down to TSC or some place and get a
couple of buckets of tranny oil. When you return, DRAIN the entire transmission, put on a new filter and change the oil. The water in there will eventually ruin the bearings and quills and cost one
hell of a lot more to replace later.

As I have gotten older, I became much smarter. In recent years, I've started forgetting all of that smart. But, that's something I still remember.
 
Ice wont drain,only water will,have you reached down into the bottom of the case and physically checked?It
could take a while to thaw in 40-50* shop.
