Bolt holding transmission in place????

I have an '86 CJ7 and when I bought it the PO said that this nut had fallen off and I should probably replace it soon with a slip resistant nut because he said it just fell off while driving his. Its a big bolt that goes through the transmission and then down through a cross member hold the transmission in place...without it, its hard to slide it into gear sometimes.

Can anyone tell me what size this nut is and if i can get it at just a random hardware store. ~Thanks

Here's a picture of the bolt.

This is the bolt that is sticking down:

The threads on this stud are 3/8 by 24 thread - easily found at a hardware store

I use a large washer on either side of the pan as well. It helps strengthen it. Also check the condition of the bushings and top nut/washer combo.

Also, this bolt doesn't hold the tranny in place. It is my understanding that it helps keep the tranny lined up under high torque conditions like hard acceleration, off-roading, etc. It does need to be anchored down so you don't accidentally tear up something else, but the actual bolts holding the tranny in place are the two bolts placed close together in the center of the skid plate.

Ok so I got a nut with a nylon washer in it and a locking washer so that maybe it doesn't fall off again, but it doesn't seem to be tightening down all the way. It threads all the way up and then I thighten more nd it never hits a stopping point. Is it suppose to be like this or is it supposed to be tight as I can get it?

Its probably spinning the bolt. Grab it on the other side with a wrench.

The stud should be straight up and down (not leaning as in the pic above). It should be tightened to the belly pan. Any play should be in the bushings above. IF the bottom nut is spinning, use a box end wrench to hold the stud be reaching in on top of the pan to hold it.

Ok yeah I had a wrench holding the top of the bolt and it was still spinning, but not real tight like I was about to torque it off....?

I to was curious about this bolt. I took it off but never put it on since the bushings where gone and the bolt rusted. I guess I will get one of these. Any Ideas in making one??
