A4LD swap out problems help

[stfree]

My old '90 4.0 4X4 Ranger was having shifting issues that forcasted failure of the A4LD in the near future. Some months ago, a friend had his '92 Explorer come to a untimely end to when a fuel leak resulted in a fire in the engine compartment. His truck was running and shifting just fine at the time of the fire and the transmission was unaffected. That tranny had a full rebuild about 8 months before using the new design upgrade parts for the A4LD.

I made a deal with him for that A4LD transmission and transfer case and pulled it about four months ago to have it on hand to replace mine. I finally got around to swapping them this week. It appeared to be a one for one swap and went without a hitch. We have everything buttoned back up but there is no joy. No motion at all, forward - reverse - nada. Dash indications for 4X4 and "low" are seemingly correct. Fluid level is correct and clean as a new.

Can anyone offer suggestions as to what we obviously missed? It's hard to believe that the donor transmission went bad sitting on my shop floor.

No Movement,,,

I would ask if when doing the swap and putting new trans in, did you MAKE SURE BEYOND A DOUBT, that the TC was on and spin it and push it in again to make it all line up nice and tight,, ? If you went under truck to install or if you pulled motor and then install as one ? If you go under truck and you dont pay very close attention and make sure TC stays put exactly where it needs to stay, that can cause issues as you describe.
