I replaced my badly torn mount today with a poly one from Energy Suspension.
But I had to drop the tranny support to get to it. In the process of putting it all back together, one of the bolts for the transmission support broke. Actually it was not the bolt, but the nut that is inside. It will come out OK, but when I tighten it, I can get it down hand-tight, and then about a quarter turn with the socket, before it starts spinning.
I'm pretty sure it ain't going anywhere and it will be OK, but just thought I'd ask you guys about it.

 

Anyone???

BTW, what do you call the fastener/nut that is inside of, or behind a wall, that you can't see or get to? But it's attached to the wall.
In my case, I'm talking about the nut that has broken loose and is spinning. You also get alot of them on trim and interior pieces.

 

Where is the exact location of the bolt you are speaking of?

 

Transmission support, drivers side, back bolt.

 

It's not the bolt. I have the same problem - one of the captive nuts (in the floorpan) for my transmission support bolts is stripped. The nut went soft (stripped) before I reached specified torque, which in my manual is 66 lb-ft. I am certain the bolt was not cross-threaded. The other nuts took the same torque and are still solid. I haven’t yet decided how to correct this. Any advice will be appreciated.
