I don't have a socket large enough to remove the transmission nut behind the center diff. I can't get my calipers in there to measure it, but it seems to be 27mm. Can anybody confirm this?
Thanks!

That sounds correct but it's been a while since I did mine, I can check when I get home from work.
if I'm not mistaken, I used a 1 1/4" socket. It was sloppy but hey, you don't need to use the nut again.
Thanks for the help; it is 27mm... a shiny new big Craftsman socket that I'll probably never use again!
You do have to re-use the nut, so I'm glad I didn't try a short-cut, especially considering I had to use the breaker bar to get it off; with my luck I would have rounded it off. Anyway, I got the trans converted to 2WD and went ahead and hooked up my K-tuned shifter!
27mm is actually a very common size. Often axle nuts, crankshaft bolts, and pulley bolts use it. Good socket to have.
When I tried to bend out the safety dimple on the axle nuts, I ended up doing more harm than good, and replaced them all for good measure. The trans nut has four dimples, so I just torqued it off so the dimples were in good shape to hammer in when it went back together. In gear, wheels chocked to keep it from rolling back and it wasnt too tough.
Bumping this thread.
What should I be torquing the trans nut down to when re-installing?
Also, the upper race is still in place and seems perfectly content to stay put. Tips on removing this thing?
I looked up torque in the FSM; don't remember off the top of my head. Don't forget to punch the safety dimples back in. My upper transfer gear bearing race came out easily with bare hands. If you don't take it out, it'll probably work it's way loose. Try chilling it?
One of those, why didn't I think of that moments.
For future searchers, it appears to be 87 ft/lb according to page 232

Tonight is supposed to be ridiculously cold. I'll check the bearing race tomorrow morning to see if it'll be more cooperative.
Temperature difference is what might help pop it off. I was thinking to apply freeze spray or ice on the steel race so it thermally contracts more that the cast aluminum tranny housing. If the entire assembly is cold soaked, it might actually be tougher to get out.
I just got back from a walk on the beach with my wife. It's 80 degrees here on Valentine's Day!
Try two strong magnets, and walk it out.
