None of the AOD transmissions are a bolt-in swap. Some have less that needs to be changed or updated than others and all require a transmission/bellhousing adapter kit (approx $900).
The AOD tranmissions from the 80's are usually easier, it's a more 'stand-alone' version than the later computer controlled ones.

If I knew more I'd tell you but I haven't really looked into it.
There are others here who are very familiar with what it takes, hopefully they'll chime in.
