There is no way that 400 is going to get in there. That auto tranny was made for the 500. You will spend thousands trying to get it to work. Just get another 500 or rebuild that one. They are pretty solid engines. Good luck!

Welcome to the forum.
I don't think Cat made an automatic 400 until 2002 and it was called the 375. So the answer to your second question is no.

The 500 and 400 use different voltage regulator and cdi unit. The auto's have a different bottom end from the manual so the drive shafts and motor mounts are also going to be different. What is wrong with the 500 motor?
I think you are going to spend big bucks to convert the quad to a 400 motor. It would be cheaper and less work to have the 500 rebuilt as long as nothing major is wrong with the 500.
