Motor swap question

I have a YJ with a 4cyl in it and I want to put a new motor in it. I don't have the mechanical know how to do so. I will be having someone do it for me. I found a 4.2 for sale but ti has an automatic trans with it. Will everything hook up to my manual tranny? Or will I have to put the auto in my jeep?

FYI, with the 4.2 you will go going to a carb, no more fuel injection. I would go to the 4.0 with fuel injection...
