@410Fortune posted excellent instructions and charts etc. Follow those and it will be no problem to use the 2000 transmission. You just have to rewire the connector, and install a new 1996 DTRS/MLPS(range sensor). Inside the pan you could also improve the trans with new solenoids etc, given the age.
The AWD transfer case you could use if you take both apart as he said, and use the back section of yours which has the VSS in it.
How many miles are on that AWD, and where is Hamilton? Those are heavy and take a large plastic tub to pack them into well. I shipped one years ago, a PITA to stuff enough firm cardboard around it in the tub.[/QUOTE
It has 210 000 kms not sure what that is in miles I am in Ontario Canada Hamilton is the city.
