That is an OBD-II system. The codes listed before, I believe were for the OBD-I Jeep systems. The codes are pretty much universal for any OBD-II system out there. You would use up Pages of space listing all the OBD-II codes.

Here's the definition you need:
Code "P0700 - Transmission Control System Malfunction"

I'd take a look at any electronic sensors or computer associated with the transmission. Sorry I can't be more help, I drive a stick :P :)

Hope that helps
