DTC P0700: EATX Controller DTC Present: Testing
This DTC is an indicator that a Trans DTC has previously been set. A code may not currently be present in the TCM if a Trans repair was made. If after reading transmission DTCs there are no codes in the TCM, this code can be erased from the PCM. If a DTC was registered in the Transmission Control Module, with the DRBIII®, go to the TCM and read codes. See appropriate DIAGNOSIS article in AUTOMATIC TRANSMISSIONS.
