frozen shifter

so again my little cj brings me a surprise in the cold. she doesnt have any problem starting first try in 0-10 degree weather but it seems like the shifter does, i had to let it warm up for about 15 minutes before i could get it out of reverse (i dont have a parking break so rev is) is this the norm, or is there somethign i can put on it to make relieve the. i just felt like i was gunna snap the shifter off. but then again its parked right next to my 2010 so i can always just take it but then i feel bad haha

Two things come to mind and I am guessing here so IMHO.

1) Gear Lube is too thick for the area you live in.

2) Water in the gear lube and it is getting up and around the shift ball and freezing.

You said CJ so my first thought is thick gear oil but you will have to have it checked and see.

Im bellow zero in utah and have somewhat the same problem. mine is do to a bad shift boot alowing water to get into the shift rails and shift tower. Ai have since replaced my boot but I was always able to rock it back and forth "letting clutch in and out" and it came free..Might need to kick the new car out of the warm garage and let the Cj thaw out. if it does not them its internal, like a stuck or bound shift fork

0-10 degrees ! If only for a day or two may not be a problem but if you have those temps for extended periods I am not sure if the 75-90 is a good choice.

How about switching to a synthetic of equivalent rating ?
Better in the cold for both the trans and the arm.

Also, like was said do you wheel this in water, if so start checking seals and gaskets.

Just thinking back when I had a Mustang and I rebuilt the trans, I thought I did a great job and basically I did but I had forgotten to torque the front seal retainer bolts which also held in the main shaft; the bolts loosened up after a few power shifts and didn’t allow the shift forks to function properly.
So thinking on this same lines, did you do any work on the trans lately, maybe a loose mounting bolt, maybe a rear mount not tight (misalignment).
Again, i am just throwing out ideas.

this can happen if your transmission is to full of oil. I a not sure why but it happened to me (filled it in the cold) You may want to check the level.

i know its not too full of oil, because i just checked it not too long ago, buts its really wierd its not stiff if rock hard like its completely locked up. then its get smoother then after its warmed up its fine. once i get back from this patrol, im gunna put her new volt reg in it so old girl will actually start to get her in my garage and drain it maybe try some synthetic or something a little thinner. is there a way to check the gasket, i have wheeled her in water a little not like snorkeling or anything but some big ditches and stuff. and mud. any advice or stories as to what you did would help./

wow you haven't fixed this yet? just change the oil and/or use a thinner oil. 5 minutes of your time and this could be done. i had the same problem and it eases up because the oil heats up as you're driving.

I don't know much about cold weather related problems but would hitting the trans case with a hair dryer or heat gun help?

I just had this problem with mine last week. Mine had a bunch of sand/dirt/water that was frozen where the shifter connects to the linkage. My shifter ended up breaking off one of the tabs. You might want to pull your shifter an plate on top of the tranny and check.
