Yessir.

Spoke w/ the shop. The replacement TC arrived late in the day so they couldn't install it - that's planned for first thing tomorrow morning.

They did pull off my TC and found a heavily damaged piece of aluminum. They/we are not sure of the proper name for this piece, but it's the chunk of metal that goes into the 4WD fork in the TC (engages it, if you will). This piece was not only damaged, but also turned roughly 90-degrees from its expected orientation.

Current working theory is that the front actuator (in the ADD) jammed due to the left-over pice of copper, and as I turned the knob to put the truck back into 2WD, the TC received erroneous input from the ADD and tried to shift the actuator at the TC, despite the front actuator still being engaged. This - either through torque transfer via the front prop shaft or via a localized (ie. in TC) mismatch between some components - caused the physical damage, and essentially locked out the entire system.

Replacement TC going in tomorrow morning.

Shop says truck is fixed! Thank goodness. What a nightmare of an ordeal.

Confirmed that they've tested 2HI/4HI/4LO and it switches fine between all driving modes.

I'm still out of town for a few days, but will try to pick up the truck late Friday eve.

Phew!

Happy it worked out.
(I still don't have a good idea how the TC actuator got broken exactly, so there is always stuff to learn....)

I'm also not totally clear on that, but so long as the truck works as it should, I'm happy. Can't wait to get it back on Friday. It's crazy how emotionally invested I am in this vehicle.

Is the transfer case and other parts covered under warranty or is the shop that installed the new gears going to pay for it?

Technically still under warranty, but practically, the shop caused the problems, so warranty doesn't really apply. Shop covered all costs.
