Answer
Hi Orly,
I disagree with the recommendation to replace the TCM. I believe that shop did not do a proper job of getting the fault code for the transmission, assuming that is the only part of the powertrain that has code. The 0700 code means simply that a second code specific to a particular problem is also stored in the trans controller memory. So they should have found a second code to be present. I would go back and tell them to try again and if they only get 0700 then there is something the matter with their code reader and they should give you back your money that you paid for the first readout. Then go to a different shop to see if they get an 0700 AND a second number (or more). The 0700 by itself doesn't tell us anything except there is another fault code that we have not been told of as yet.
Please read the PS below.
