Will today be the day that the transmission and transfer case go into the chassis? Barring any major complications, I sure hope so. Using my trusty shop crane, I was able to lift the transmission and transfer case at an acceptable angle. It took some coaxing and rotating things, but I eventually got things lined up.

The transmission and transfer case are now in the chassis.

Thought this was an interesting shot. I reconditioned the tags that go on the bolt for the intermediate shaft lock plate. Maybe it's not that interesting...

Dana tags for serial number and something else.

Seeing the transmission and transfer case in the chassis makes me feel like I'm really making some progress. Still a lot of stuff to do, but it looks nice sitting in the frame finally. Also, it's really freed up a lot of space in the garage.

Angled view of the transmission and transfer case in the chassis.

Something that took me some research to figure out was how the heck the transmission mount, torque bar and torque pin all attach to the transmission adapter housing and the skid plate. The skid plate is essentially what support the transmission and transfer case, in addition to the assembly being connected to the engine.

There is surprisingly little documentation on how this goes together and detailed photos are few and far in between. Hopefully I got this right and someone can benefit from these photo records - again, provided I've done this correctly. Looking at my old photos from disassembly, I did an OK job recording that process, so I had enough to go on to put things back together.

The torque bar sits on top of the transmission mount and one bolt goes through the transmission mount top plate, through the torque bar and into 1 of 3 holes in the transmission adapter housing. A separate bolt goes next to the transmission mount, only going through the torque bar and into another hole in the transmission adapter housing.

On the far passenger side of the torque bar, a bolt goes through the transmission mount top plate, through the torque bar and that's it - it's held on the top side with a lock washer and nut.

The above was pretty intuitive once you saw how everything lines up. The torque pin is not so obvious since few photos exist. The new bushings are polyurethane and should last longer and perform better than rubber ones. They are identical and one goes above the torque bar and the other goes below it. On top, there is a thick washer and locknut to hold the top part together. On the bottom, another thick washer sits below the lower bushing and is held against the 3/4" nut that is part of the pin.

Below this another washer is placed, but on top of the skid plate.

Torque pin assembly order.

The torque pin goes through the skid plate where 2 washers are stacked and held on with a lock nut. This is how I recall it from my disassembly photos. Apparently, this assembly is there to allow the transmission and transfer case to move with the engine as it moves and shifts under load, but then limits the movement so that things don't twist and break.

With everything assembled, there is still a gap between the bushings, but I'm told that this is normal and part of the design. Just strange. It's also strange that only 2 bolts actually hold the transmission and transfer case to the mount. As you can see below, the bottom side of the mount sits on top of the skid plate and accepts 2 bolts (7/16"-14tpi coarse thread, 1" long) to secure it. This is a new polyurethane mount from Daystar. The original was rubber and had 2 studs sticking down through the skid plate and nuts were threaded on to hold things in place.
