First thing? Reset codes and see what comes back. How? Either use a scanner or disconnect the negative battery cable for 2-3 minutes.
P0700 is telling you the TCM (EATX Controller) may have detected a fault and stored a code. Have the TCM code read by a shop with a specialised scanner capable of reading transmission codes.
