Transmission swap is mechanically complete, just got to get the bird nest of wires where they're supposed to be. The part I've been dreading the most.
Haven't taken many pics, since it's been a dirty job, but do have a few.
The 4L80E is a good bit longer than the NV4500, so there was some modding that needed to be done.

In the above pic, the trans cross member is slid as far back as it will go, because I had to cut the NV4500 mount off, and use the center hole in the cross member, which lined it back up with the rear most holes in the frame.
Then the driveshaft had to be addressed, as pointed out in the other thread I made. Here's the two I was working with. Out of frame, but the ends that bolt to the trans are flush with each other, to show the difference in length of the front shafts.

I wound up using the front shaft from the ECLB, and rear shaft from the RCLB. Worked great.

I did jack the rear up, and see if I had movement in all the gears, which I do, thankfully.
Now I need to quit stalling, and go tackle that wiring.
