So 2day i was driving and i went over the train tracks very slowly and after two blocks down my light comes on and its a p0700 ( Transaxel Control System Malfunction) so what does that mean?

Does it shift OK? I would check the connectors for the TCM/ATX. If all is clean and tight yor TCM prolly has taken a dump. Not sure, exactly how/where they are on the '02's

Ya it shifts when its supposed to, but when in checked under the hood the right side of the transmission cooler line had oil al around it, even at the bottom of my tranny pan.

Did you check the fluid? If there's a leak its probably whats causing the code

It would slip before a leak set the CEL. There are no "leak detectors" tho it would be nice. Generally that is called a weekly inspection.
Try resetting the PCM, and see if it comes back. I would replace the cooler lines before they do have a catastrophic failure. It could just be wear, but usually the ATX goes into limp mode if too much fluid volume is needed to engage the clutches. (It is measured every time) It will shift into 2nd gear and stay there. Then the car needs to be shut off and restarted after a minute or two and it will shift normal for a little while then do it again. Sometimes it is the TCM, but most times the ATX is done. You may as well take it to the dealer and have them look into it if it comes back. My Mom's Concorde did the same thing and it was the TCM/related and $80.00 later she was on her way. Just never know.
