Sounds like you need to replace your atx mounts. If your money is tight, go with oem mounts for the mean time. I'll look in my haynes manuel, since we both have an atx. but the chiltons is better more in depth info.
Update: haynes only have codes P0700 and P0703
Doesn't give in depth info like the Chiltons book
Haynes:
P0700----Automatic Transaxle fault detected P0703----Brake switch stuck open or closed
These two are stated from the Haynes manuel.
I recommend for you to pickup a copy of the Chiltons manuel, I bet it has all of the trouble codes.
If there's more serious problems with your ATX, do the MTX swap.
But, drive the atx for awhile until you have all the parts for the swap. If you don't have a backup ride, but if you already have an extra ride, do the mtx swap.
Use the search for the mtx swap tons of great info, and theres a write up with pics.
