P0700 is the TCM requesting a MIL (Malfunction Indicator Light aka: "check engine"). All the 700 code does is tell the ECM "something's wrong" and to illuminate the MIL. There is another code in the TCM that you need to pull that will actually tell you what the malfunction is so.
Like said above I go to a local parts store to have code read for free. If one place can't read it I go to another. Seems like there all stack up in a row by us.
Report back with code.
