First up what motor do you have, 3vze or 22re?
If you are up to it you can convert it to a manual with relative simplicity. Look on here or yotatech for write ups, there are plenty. I've done it myself, however I never did a write up. One thing that will help you immensely is to get a whole donor vehicle, that's how I did mine.
If you do swap feel free to ask any questions you might have.
