Transmission is completely frozen

Here's a good for you guys. I started my tj (2000, 4.0, 5spd) recently when it was about 10f out. I did my normal thing with a manual: put xfer case in neutral, transmission in 3rd, and wanted to let it idle for 10-20 minutes. But, when i let the clutch out it died. So i tried again with the transmission in neutral, and it died again.

I'm thinking it's frozen. After holding the clutch and letting it idle for around 10 minutes, it freed up. BTW, I'm in oklahoma, and it just finally dropped way below freezing. Since I got my jeep (has about 65000 miles on it now, I've put 5k ish on it) Ive easily driven 400-600 miles up and down the South Canadian and Cimarron rivers. Is it possible to actually freeze up a transmission this bad? After it freed up I could drive it like normal, with no issues to speak of. Also, after letting it sit a while, I pulled the drain plug and saw no water.

It's just baffling me since the shaft that spins in neutral is quite a ways above where the water line could possibly be.

Thanks guys

That's an odd one. Maybe it has wrong lubricant. Do a change, preferrably synthetic if available for that trans.

Unless you have water in the transmission, no it's not possible at 10 degrees.

My 04 has not had any issues with the cold and it has been way below freezing where I am (in Oklahoma) for several days. I have Royal Purple in my tranny maybe it's time for a drain and fill?

Hasn't happened to me and I'm regularly in single digit weather for weeks straight.
One time I had really thick gear lube in there and you could feel the increased viscosity in the form of drag but it never stalled out because of it.

I'll change the oil. It's unreal that it could freeze that solid without cracking the case.

That said, anybody have opinions on the best way to change out the jiggle cap breather for a real breather.

Id look into the clutch first.... check the fluid in it. To me it sounds like a clutch issue over tranny.
