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.

Would this cause the light to come on when driving down the road. I put the vehicle in neutral than turn the key off just to check to see if it would shut the engine off but it didnt just the power. Than turned it back to run and put it back in drive.
Than when I got to where is was going got back in vehicle turned it on and the engine light came on.

Than I took it to auto zone got it reset and it hasnt came back on since.

Yes it could cause the engine light to come on and it may have just been an intermittent issue, if the light doesn't come back on then wouldn't worry about it. If it comes back then need to run a diagnostic on the tranny.
