A year? And the engine hasn't blown up? You have one of the really tough ones.

Code 700 means there's some other diagnostic fault code stored in the Transmission Computer. That will put it in "limp mode" where it stays in second gear to allow you to drive it slowly to a repair shop without needing a tow truck. 30 mph would be pushing it.

P0340 – Camshaft Position Sensor Circuit Malfunction
P0605 – Internal Control Module Read Only Memory ROM) Error

I don't even know where to start with the two engine fault codes. The first thing to do is have the code in the Transmission Computer read. That will require a full scanner; not the simple code readers used at many auto parts stores. Once we know what's causing it to go to limp mode we can make some informed decisions on how to proceed.
