You'll need to take this to the pros.The P0700 is a code to let the tecnician know that there are codes stored in the TCM (trans control module)The p0605 is an internal computer fault in the ROM (Read only memory)chip.That may only require what is called a flash update to fix.At any rate it's not something you will be able to handle at home as it requires special tools and equipment to diagnose.
