Transmission question

I have searched but haven't found the specific info I'm looking for. My question is I have an 83zx with a trans going bad. I have an 83zxt that is sitting in my back yard. I got my local mechanic to take the zxt trans off along with the 280zx trans. He's found a couple of differences but mainly the oil line holes on the zx are not on the zxt. My question is do i have to modify the zxt trans or can I just have him install it the way it is. What about the electrical connections on it? any advise would be welcomed and appreciated.

I forgot to mentioned they are both automatics.
