I pride myself in doing my own work, but unfortunately have fallen behind on giving my wife's mall crawler the love it deserves.
We are heading out of town tomorrow, but her parents are coming to stay with my daughter while we are gone. He is a lifelong farmer who has pretty impressive mechanical abilities. I've turned wrenches with him on many industrial machines.
I haven't done anything beyond changing the oil, and it just hit 50K. I figure I should leave him the following instructions and have him perform the below tasks with the transmission being the priority. Can you guys keep me honest?
Transmission fluid:
Do this one first, and follow the instructions below. I assume he can get a nice synthetic fluid at the auto parts store of his choice. Looks like he'll also need three gaskets from the dealership, and if he can't find my bottle pump he'll want to buy a new one.

Parts:

Manual says 3.2 qts for a drain and fill, but on my other Toyota I've always gotten more than what the manual said and ~4 qts has been reported in the 4th gen forum

Special tools:

Transfer case:
Use the instructions below. I assume he can buy the gear oil at the auto parts store, and doesn't need the Toyota stuff.
Torque specs:
Drain plug - 27 lb-ft (24mm or 15/16")
Fill plug - 27 lb-ft (24mm or 15/16")

Tips:
1) Ensure you can remove fill plug before draining
2) After filling, leave plug out and let sit ~5 minutes and re-check, add if necessary
3) Diff and xfer case gasket kit

Buy about five quarts of this from Advance Auto

And buy this from Toyota while he is getting the gaskets for the transmission.
