Well, if you have a donor vehicle the swap should be relatively easy. Just keep grabbing parts off of the standard until the one with the automatic becomes standard. Short of that, I think the swap will be pretty complex seeing that there are obvious difference in pedals and then there is the body cutout around the stick that has the shifter boot which will need to come over from the standard.

The easiest would be to just replace the auto with another auto. Going to a standard would be complex. It would be almost mandatory to have a donor vehicle to make the swap. Buying it piece by piece would lead to astronomical costs.

The body side of the parts needed could be gotten from either a 4cyl or a 6cyl, since they are the same. But the drivetrain parts needed would have to match the motor. Such as the flywheel, starter, bell housing, trans, t-case, skid plate, drive shafts, and I'm sure I have missed a few parts along the way.

Are you dealing with a 6 cylinder or 4 cylinder? What year YJ?

The auto to manual swap is one of my least favorite endeavors....as the collection of parts is significant, but don't let that dissuade you from the swap, if you are mechanically inclined it can be done over a couple of weekends. If you don't want the hassle of finding and buying a parts vehicle, there are always lots of people parting out YJ's....find one locally and work a deal to pull the parts yourself! Taking the parts off, makes figuring out where they go that much easier!

If you are dealing with a 4 cylinder, I would say bite the bullet and swap the whole drivetrain to a 6 cylinder and a stick shift, in the long run it probably won't take significantly more time.
