The short answer, not to be an internet troll, is to sell it and buy a manual.
In order for you to do a manual swap, you'll need essentially every wiring harness/device out of the donor car as well, otherwise the computer will freak out and not be happy (or remove all factory components and do a standalone engine management system).
Since these cars are so old, the resale has tanked, so you can get a T5 w/ a manual for not much.
Otherwise, just enjoy what you currently have, unfortunately 01-02's are prone to automatic transmission issues, so just be aware of that.
Sorry to be the bearer of bad news, but a manual swap on these cars is nowhere near simple nor cost effective in the large scope of things
