Try disconnecting the battery and the TCM for 30mins and then reconnect and see what happens-Most likely its gonna be the TCM if the code returns-

A code P0700 in the PCM, is nothing other than an informative code, that indicates the transmission control module has requested the MIL(check engine light) to illuminate. From there, you would need to request fault codes from the TCM. This does not indicate you have a transmission control module that is faulty. Since the transmission control module can not illuminate the light itself, it requests the PCM to do it, and sets this code. You need to take it one step further, and find out what DTC(s) are present in the TCM. The PCM is located on a bracket over the RH(passenger) side cam cover.
