P0700 is EATX code present.

It simply means that the engine computer has noticed that the transmission computer has a dtc in it. This causes the Pcm (engine computer) to turn the check engine light on. You will need to have the TCM (trans computer) checked for codes to know what to diagnose.
General automatic transmission fault. It could be a sticky internal sensor. A transmission shop could read the actual fault from the transmission.
